Web API fuzzing runs in the `fuzz` stage of the CI/CD pipeline. To ensure API fuzzing scans the
latest code, your CI/CD pipeline should deploy changes to a test environment in one of the stages
preceding the `fuzz` stage.
Note the following changes have been made to the API fuzzing template:
- In GitLab 14.0 and later, you must define a `fuzz` stage in your `.gitlab-ci.yml` file.
- In GitLab 13.12 and earlier, the API fuzzing template defines `build`, `test`, `deploy`, and
`fuzz` stages. The `fuzz` stage runs last by default. The predefined stages were deprecated, and removed from the `API-Fuzzing.latest.gitlab-ci.yml` template. They will be removed in a future GitLab
version.
If your pipeline is configured to deploy to the same web server on each run, running a
pipeline while another is still running could cause a race condition in which one pipeline
overwrites the code from another. The API to scan should be excluded from changes for the duration
of a fuzzing scan. The only changes to the API should be from the fuzzing scanner. Any changes made
to the API (for example, by users, scheduled tasks, database changes, code changes, other pipelines,
or other scanners) during a scan could cause inaccurate results.
You can run a Web API fuzzing scan using the following methods:
A media type (formerly known as MIME type) is an identifier for file formats and format contents transmitted. A OpenAPI document lets you specify that a given operation can accept different media types, hence a given request can send data using different file content. As for example, a `PUT /user` operation to update user data could accept data in either XML (media type `application/xml`) or JSON (media type `application/json`) format.
OpenAPI 2.x lets you specify the accepted media types globally or per operation, and OpenAPI 3.x lets you specify the accepted media types per operation. API Fuzzing checks the listed media types and tries to produce sample data for each supported media type.
- In [GitLab 14.10 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/333304), the default behavior is to select one of the supported media types to use. The first supported media type is chosen from the list. This behavior is configurable.
- In GitLab 14.9 and earlier, the default behavior is to perform testing using all supported media types. This means if two media types are listed (for example, `application/json` and `application/xml`), tests are performed using JSON, and then the same tests using XML.
Testing the same operation (for example, `POST /user`) using different media types (for example, `application/json` and `application/xml`) is not always desirable.
For example, if the target application executes the same code regardless of the request content type, it will take longer to finish the test session, and it may report duplicate vulnerabilities related to the request body depending on the target app.
The environment variable `FUZZAPI_OPENAPI_ALL_MEDIA_TYPES` lets you specify whether or not to use all supported media types instead of one when generating requests for a given operation. When the environmental variable `FUZZAPI_OPENAPI_ALL_MEDIA_TYPES` is set to any value, API Fuzzing will try to generate requests for all supported media types instead of one in a given operation. This will cause testing to take longer as testing is repeated for each provided media type.
Alternatively, the variable `FUZZAPI_OPENAPI_MEDIA_TYPES` is used to provide a list of media types that will each be tested. Providing more than one media type causes testing to take longer, as testing is performed for each media type selected. When the environment variable `FUZZAPI_OPENAPI_MEDIA_TYPES` is set to a list of media types, only the listed media types are included when creating requests.
Multiple media types in `FUZZAPI_OPENAPI_MEDIA_TYPES` must separated by a colon (`:`). For example, to limit request generation to the media types `application/x-www-form-urlencoded` and `multipart/form-data`, set the environment variable `FUZZAPI_OPENAPI_MEDIA_TYPES` to `application/x-www-form-urlencoded:multipart/form-data`. Only supported media types in this list are included when creating requests, though unsupported media types are always skipped. A media type text may contain different sections. For example, `application/vnd.api+json; charset=UTF-8` is a compound of `type "/" [tree "."] subtype ["+" suffix]* [";" parameter]`. Parameters are not taken into account when filtering media types on request generation.
The environment variables `FUZZAPI_OPENAPI_ALL_MEDIA_TYPES` and `FUZZAPI_OPENAPI_MEDIA_TYPES` allow you to decide how to handle media types. These settings are mutually exclusive. If both are enabled, API Fuzzing reports an error.

Postman has grown from a basic client tool with a nice UX experience to a more complex ecosystem that allows testing APIs with scripts, creating complex collections that trigger secondary requests, and setting variables along the way. Not every feature in the Postman ecosystem is supported. For example, scripts are not supported. The main focus of the Postman support is to ingest Postman Collection definitions that are used by the Postman Client and their related variables defined in the workspace, environments, and the collections themselves.
Postman allows creating variables in different scopes. Each scope has a different level of visibility in the Postman tools. For example, you can create a variable in a _global environment_ scope that is seen by every operation definition and workspace. You can also create a variable in a specific _environment_ scope that is only visible and used when that specific environment is selected for use. Some scopes are not always available, for example in the Postman ecosystem you can create requests in the Postman Client, these requests do not have a _local_ scope, but test scripts do.
Variable scopes in Postman can be a daunting topic and not everyone is familiar with it. We strongly recommend that you read [Variable Scopes](https://learning.postman.com/docs/sending-requests/variables/#variable-scopes) from Postman documentation before moving forward.
As mentioned above, there are different variable scopes, and each of them has a purpose and can be used to provide more flexibility to your Postman document. There is an important note on how values for variables are computed, as per Postman documentation:
> If a variable with the same name is declared in two different scopes, the value stored in the variable with narrowest scope is used. For example, if there is a global variable named `username` and a local variable named `username`, the local value is used when the request runs.
The following is a summary of the variable scopes supported by the Postman Client and API Fuzzing:
- **Global Environment (Global) scope** is a special pre-defined environment that is available throughout a workspace. We can also refer to the _global environment_ scope as the _global_ scope. The Postman Client allows exporting the global environment into a JSON file, which can be used with API Fuzzing.
- **Environment scope** is a named group of variables created by a user in the Postman Client.
The Postman Client supports a single active environment along with the global environment. The variables defined in an active user-created environment take precedence over variables defined in the global environment. The Postman Client allows exporting your environment into a JSON file, which can be used with API Fuzzing.
- **Collection scope** is a group of variables declared in a given collection. The collection variables are available to the collection where they have been declared and the nested requests or collections. Variables defined in the collection scope take precedence over the _global environment_ scope and also the _environment_ scope.
The Postman Client can export one or more collections into a JSON file, this JSON file contains selected collections, requests, and collection variables.
- **API Fuzzing Scope** is a new scope added by API Fuzzing to allow users to provide extra variables, or override variables defined in other supported scopes. This scope is not supported by Postman. The _API Fuzzing Scope_ variables are provided using a [custom JSON file format](#api-fuzzing-scope-custom-json-file-format).
- Override values defined in the environment or collection
- Defining variables from scripts
- Define a single row of data from the unsupported _data scope_
- **Data scope** is a group of variables in which their name and values come from JSON or CSV files. A Postman collection runner like [Newman](https://learning.postman.com/docs/running-collections/using-newman-cli/command-line-integration-with-newman/) or [Postman Collection Runner](https://learning.postman.com/docs/running-collections/intro-to-collection-runs/) executes the requests in a collection as many times as entries have the JSON or CSV file. A good use case for these variables is to automate tests using scripts in Postman.
API Fuzzing does **not** support reading data from a CSV or JSON file.
- **Local scope** are variables that are defined in Postman scripts. API Fuzzing does **not** support Postman scripts and by extension, variables defined in scripts. You can still provide values for the script-defined variables by defining them in one of the supported scopes, or our custom JSON format.
Not all scopes are supported by API Fuzzing and variables defined in scripts are not supported. The following table is sorted by broadest scope to narrowest scope.
- [Defining global variables](https://learning.postman.com/docs/sending-requests/variables/#defining-global-variables)
##### Exporting from Postman Client
The Postman Client lets you export different file formats, for instance, you can export a Postman collection or a Postman environment.
The exported environment can be the global environment (which is always available) or can be any custom environment you previously have created. When you export a Postman Collection, it may contain only declarations for _collection_ and _local_ scoped variables; _environment_ scoped variables are not included.
To get the declaration for _environment_ scoped variables, you have to export a given environment at the time. Each exported file only includes variables from the selected environment.
For more details on exporting variables in different supported scopes, see:
- [Downloading global environments](https://learning.postman.com/docs/sending-requests/variables/#downloading-global-environments)
##### API Fuzzing Scope, custom JSON file format
Our custom JSON file format is a JSON object where each object property represents a variable name and the property value represents the variable value. This file can be created using your favorite text editor, or it can be produced by an earlier job in your pipeline.
This example defines two variables `base_url` and `token` in the API Fuzzing scope:
```json
{
"base_url": "http://127.0.0.1/",
"token": "Token 84816165151"
}
```
##### Using scopes with API Fuzzing
The scopes: _global_, _environment_, _collection_, and _GitLab API Fuzzing_ are supported in [GitLab 15.1 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/356312). GitLab 15.0 and earlier, supports only the _collection_, and _GitLab API Fuzzing_ scopes.
The following table provides a quick reference for mapping scope files/URLs to API Fuzzing configuration variables:
| Scope | How to Provide |
| ------------------ | --------------- |
| Global Environment | FUZZAPI_POSTMAN_COLLECTION_VARIABLES |
| API Fuzzing Scope | FUZZAPI_POSTMAN_COLLECTION_VARIABLES |
| Data | Not supported |
| Local | Not supported |
The Postman Collection document automatically includes any _collection_ scoped variables. The Postman Collection is provided with the configuration variable `FUZZAPI_POSTMAN_COLLECTION`. This variable can be set to a single [exported Postman collection](https://learning.postman.com/docs/getting-started/importing-and-exporting-data/#exporting-collections).
Variables from other scopes are provided through the `FUZZAPI_POSTMAN_COLLECTION_VARIABLES` configuration variable. The configuration variable supports a comma (`,`) delimited file list in [GitLab 15.1 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/356312). GitLab 15.0 and earlier, supports only one single file. The order of the files provided is not important as the files provide the needed scope information.
The configuration variable `FUZZAPI_POSTMAN_COLLECTION_VARIABLES` can be set to:
- [Exported Global environment](https://learning.postman.com/docs/sending-requests/variables/#downloading-global-environments)
There is a chance that API Fuzzing engine does not find all variables references that your Postman collection file is using. Some cases can be:
- You are using _data_ or _local_ scoped variables, and as stated previously these scopes are not supported by API Fuzzing. Thus, assuming the values for these variables have not been provided through [the API Fuzzing scope](#api-fuzzing-scope-custom-json-file-format), then the values of the _data_ and _local_ scoped variables are undefined.
- A variable name was typed incorrectly, and the name does not match the defined variable.
- Postman Client supports a new dynamic variable that is not supported by API Fuzzing.
When possible, API Fuzzing follows the same behavior as the Postman Client does when dealing with undefined variables. The text of the variable reference remains the same, and there is no text substitution. The same behavior also applies to any unsupported dynamic variables.
For example, if a request definition in the Postman Collection references the variable `{{full_url}}` and the variable is not found it is left unchanged with the value `{{full_url}}`.
##### Dynamic Postman variables
In addition to variables that a user can define at various scope levels, Postman has a set of pre-defined variables called _dynamic_ variables. The [_dynamic_ variables](https://learning.postman.com/docs/writing-scripts/script-references/variables-list/) are already defined and their name is prefixed with a dollar sign (`$`), for instance, `$guid`. _Dynamic_ variables can be used like any other variable, and in the Postman Client, they produce random values during the request/collection run.
An important difference between API Fuzzing and Postman is that API Fuzzing returns the same value for each usage of the same dynamic variables. This differs from the Postman Client behavior which returns a random value on each use of the same dynamic variable. In other words, API Fuzzing uses static values for dynamic variables while Postman uses random values.
The supported dynamic variables during the scanning process are:
| `$randomLoremLines` | `Ducimus in ut mollitia.\nA itaque non.\nHarum temporibus nihil voluptas.\nIste in sed et nesciunt in quaerat sed.` |
| `$randomLoremParagraph` | `Ab aliquid odio iste quo voluptas voluptatem dignissimos velit. Recusandae facilis qui commodi ea magnam enim nostrum quia quis. Nihil est suscipit assumenda ut voluptatem sed. Esse ab voluptas odit qui molestiae. Rem est nesciunt est quis ipsam expedita consequuntur.` |
| `$randomLoremParagraphs` | `Voluptatem rem magnam aliquam ab id aut quaerat. Placeat provident possimus voluptatibus dicta velit non aut quasi. Mollitia et aliquam expedita sunt dolores nam consequuntur. Nam dolorum delectus ipsam repudiandae et ipsam ut voluptatum totam. Nobis labore labore recusandae ipsam quo.` |
| `$randomLoremSentence` | `Molestias consequuntur nisi non quod.` |
| `$randomLoremSentences` | `Et sint voluptas similique iure amet perspiciatis vero sequi atque. Ut porro sit et hic. Neque aspernatur vitae fugiat ut dolore et veritatis. Ab iusto ex delectus animi. Voluptates nisi iusto. Impedit quod quae voluptate qui.` |
| `$randomLoremText` | `Quisquam asperiores exercitationem ut ipsum. Aut eius nesciunt. Et reiciendis aut alias eaque. Nihil amet laboriosam pariatur eligendi. Sunt ullam ut sint natus ducimus. Voluptas harum aspernatur soluta rem nam.` |
In this example, [the _global_ scope is exported](https://learning.postman.com/docs/sending-requests/variables/#downloading-global-environments) from the Postman Client as `global-scope.json` and provided to API Fuzzing through the `FUZZAPI_POSTMAN_COLLECTION_VARIABLES` configuration variable.
In this example, [the _environment_ scope is exported](https://learning.postman.com/docs/getting-started/importing-and-exporting-data/#exporting-environments) from the Postman Client as `environment-scope.json` and provided to API Fuzzing through the `FUZZAPI_POSTMAN_COLLECTION_VARIABLES` configuration variable.
Here is an example of using `FUZZAPI_POSTMAN_COLLECTION_VARIABLES`:
The _collection_ scope variables are included in the exported Postman Collection file and provided through the `FUZZAPI_POSTMAN_COLLECTION` configuration variable.
Here is an example of using `FUZZAPI_POSTMAN_COLLECTION`:
The API Fuzzing Scope is used for two main purposes, defining _data_ and _local_ scope variables that are not supported by API Fuzzing, and changing the value of an existing variable defined in another scope. The API Fuzzing Scope is provided through the `FUZZAPI_POSTMAN_COLLECTION_VARIABLES` configuration variable.
Here is an example of using `FUZZAPI_POSTMAN_COLLECTION_VARIABLES`:
The file `api-fuzzing-scope.json` uses our [custom JSON file format](#api-fuzzing-scope-custom-json-file-format). This JSON is an object with key-value pairs for properties. The keys are the variables' names, and the values are the variables'
In this example, a _global_ scope, _environment_ scope, and _collection_ scope are configured. The first step is to export our various scopes.
- [Export the _global_ scope](https://learning.postman.com/docs/sending-requests/variables/#downloading-global-environments) as `global-scope.json`
- [Export the _environment_ scope](https://learning.postman.com/docs/getting-started/importing-and-exporting-data/#exporting-environments) as `environment-scope.json`
- Export the Postman Collection which includes the _collection_ scope as `postman-collection.json`
The Postman Collection is provided using the `FUZZAPI_POSTMAN_COLLECTION` variable, while the other scopes are provided using the `FUZZAPI_POSTMAN_COLLECTION_VARIABLES`. API Fuzzing can identify which scope the provided files match using data provided in each file.
When using exported scopes, it's often the case that the value of a variable must be changed for use with API Fuzzing. For example, a _collection_ scoped variable might contain a variable named `api_version` with a value of `v2`, while your test needs a value of `v1`. Instead of modifying the exported collection to change the value, the API Fuzzing scope can be used to change its value. This works because the _API Fuzzing_ scope takes precedence over all other scopes.
The _collection_ scope variables are included in the exported Postman Collection file and provided through the `FUZZAPI_POSTMAN_COLLECTION` configuration variable.
The API Fuzzing Scope is provided through the `FUZZAPI_POSTMAN_COLLECTION_VARIABLES` configuration variable, but first, we must create the file.
The file `api-fuzzing-scope.json` uses our [custom JSON file format](#api-fuzzing-scope-custom-json-file-format). This JSON is an object with key-value pairs for properties. The keys are the variables' names, and the values are the variables'
##### Example: Changing a Variables Value with Multiple Scopes
When using exported scopes, it's often the case that the value of a variable must be changed for use with API Fuzzing. For example, an _environment_ scope might contain a variable named `api_version` with a value of `v2`, while your test needs a value of `v1`. Instead of modifying the exported file to change the value, the API Fuzzing scope can be used. This works because the _API Fuzzing_ scope takes precedence over all other scopes.
In this example, a _global_ scope, _environment_ scope, _collection_ scope, and _API Fuzzing_ scope are configured. The first step is to export and create our various scopes.
- [Export the _global_ scope](https://learning.postman.com/docs/sending-requests/variables/#downloading-global-environments) as `global-scope.json`
- [Export the _environment_ scope](https://learning.postman.com/docs/getting-started/importing-and-exporting-data/#exporting-environments) as `environment-scope.json`
- Export the Postman Collection which includes the _collection_ scope as `postman-collection.json`
The API Fuzzing scope is used by creating a file `api-fuzzing-scope.json` using our [custom JSON file format](#api-fuzzing-scope-custom-json-file-format). This JSON is an object with key-value pairs for properties. The keys are the variables' names, and the values are the variables'
values. For example:
```json
{
"api_version": "v1"
}
```
The Postman Collection is provided using the `FUZZAPI_POSTMAN_COLLECTION` variable, while the other scopes are provided using the `FUZZAPI_POSTMAN_COLLECTION_VARIABLES`. API Fuzzing can identify which scope the provided files match using data provided in each file.
The API fuzzing behavior can be changed through CI/CD variables.
From GitLab 13.12 and later, the default API fuzzing configuration file is `.gitlab/gitlab-api-fuzzing-config.yml`. In GitLab 14.0 and later, API fuzzing configuration files must be in your repository's
`.gitlab` directory instead of your repository's root.
If you do not want to Base64-encode the password (or if you are using GitLab 15.3 or earlier) you can provide the raw password `FUZZAPI_HTTP_PASSWORD`, instead of using `FUZZAPI_HTTP_PASSWORD_BASE64`.
| `FUZZAPI_API_PORT` | Specify the communication port number used by API Fuzzing engine. Defaults to `5500`. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/367734) in GitLab 15.5. |
|[`FUZZAPI_EXCLUDE_URLS`](#exclude-urls) | Exclude API URL from testing. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/357195) in GitLab 14.10. |
|[`FUZZAPI_EXCLUDE_PARAMETER_FILE`](#exclude-parameters) | Path to a JSON file containing excluded parameters. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/292196) in GitLab 14.10. |
|[`FUZZAPI_OPENAPI_ALL_MEDIA_TYPES`](#openapi-specification) | Use all supported media types instead of one when generating requests. Causes test duration to be longer. Default is disabled. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/333304) in GitLab 14.10. |
|[`FUZZAPI_OPENAPI_MEDIA_TYPES`](#openapi-specification) | Colon (`:`) separated media types accepted for testing. Default is disabled. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/333304) in GitLab 14.10. |
|[`FUZZAPI_GRAPHQL`](#graphql-schema) | Path to GraphQL endpoint, for example `/api/graphql`. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/352780) in GitLab 15.4. |
|[`FUZZAPI_GRAPHQL_SCHEMA`](#graphql-schema) | A URL or filename for a GraphQL schema in JSON format. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/352780) in GitLab 15.4. |
|[`FUZZAPI_POSTMAN_COLLECTION_VARIABLES`](#postman-variables) | Path to a JSON file to extract Postman variable values. The support for comma-separated (`,`) files was [introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/356312) in GitLab 15.1. |
|[`FUZZAPI_OVERRIDES_CMD_VERBOSE`](#overrides) | When set to any value. It shows overrides command output as part of the job output. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/334578) in GitLab 14.8. |
|`FUZZAPI_PRE_SCRIPT` | Run user command or script before scan session starts. |
|`FUZZAPI_POST_SCRIPT` | Run user command or script after scan session has finished. |
To provide the overrides JSON as a file, the `FUZZAPI_OVERRIDES_FILE` CI/CD variable is set. The path is relative to the job current working directory.
To execute scripts in Alpine Linux you must first use the command [`chmod`](https://www.gnu.org/software/coreutils/manual/html_node/chmod-invocation.html) to set the [execution permission](https://www.gnu.org/software/coreutils/manual/html_node/Setting-Permissions.html). For example, to set the execution permission of `script.py` for everyone, use the command: `chmod a+x script.py`. If needed, you can version your `script.py` with the execution permission already set.
By default the output of the overrides command is hidden. If the overrides command returns a non zero exit code, the command is displayed as part of your job output. Optionally, you can set the variable `FUZZAPI_OVERRIDES_CMD_VERBOSE` to any value to display overrides command output as it is generated. This is useful when testing your overrides script, but should be disabled afterwards as it slows down testing.
It is also possible to write messages from your script to a log file that is collected when the job completes or fails. The log file must be created in a specific location and follow a naming convention.
Adding some basic logging to your overrides script is useful in case the script fails unexpectedly during normal running of the job. The log file is automatically included as an artifact of the job, allowing you to download it after the job has finished.
Following our example, we provided `renew_token.py` in the environmental variable `FUZZAPI_OVERRIDES_CMD`. Please notice two things in the script:
- Log file is saved in the location indicated by the environment variable `CI_PROJECT_DIR`.
# logs informing override has finished successfully
logging.info("Override file has been updated")
# end
```
In the overrides command example, the Python script depends on the `backoff` library. To make sure the library is installed before executing the Python script, the `FUZZAPI_PRE_SCRIPT` is set to a script that will install the dependencies of your overrides command.
As for example, the following script `user-pre-scan-set-up.sh`:
In the previous sample, you could use the script `user-pre-scan-set-up.sh` to also install new runtimes or applications that later on you could use in your overrides command.
When testing an API it can be useful to exclude certain paths. For example, you might exclude testing of an authentication service or an older version of the API. To exclude paths, use the `FUZZAPI_EXCLUDE_PATHS` CI/CD variable . This variable is specified in your `.gitlab-ci.yml` file. To exclude multiple paths, separate entries using the `;` character. In the provided paths you can use a single character wildcard `?` and `*` for a multiple character wildcard.
To verify the paths are excluded, review the `Tested Operations` and `Excluded Operations` portion of the job output. You should not see any excluded paths listed under `Tested Operations`.
```plaintext

#### Examples of excluding paths
This example excludes the `/auth` resource. This does not exclude child resources (`/auth/child`).
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/292196) in GitLab 14.10.
While testing an API you may might want to exclude a parameter (query string, header, or body element) from testing. This may be needed because a parameter always causes a failure, slows down testing, or for other reasons. To exclude parameters you can use one of the following variables: `FUZZAPI_EXCLUDE_PARAMETER_ENV` or `FUZZAPI_EXCLUDE_PARAMETER_FILE`.
The `FUZZAPI_EXCLUDE_PARAMETER_ENV` allows providing a JSON string containing excluded parameters. This is a good option if the JSON is short and will not often change. Another option is the variable `FUZZAPI_EXCLUDE_PARAMETER_FILE`. This variable is set to a file path that can be checked into the repository, created by another job as an artifact, or generated at runtime from a pre script using `FUZZAPI_PRE_SCRIPT`.
#### Exclude parameters using a JSON document
The JSON document contains a JSON object which uses specific properties to identify which parameter should be excluded.
You can provide the following properties to exclude specific parameters during the scanning process:
-`headers`: Use this property to exclude specific headers. The property's value is an array of header names to be excluded. Names are case-insensitive.
-`cookies`: Use this property's value to exclude specific cookies. The property's value is an array of cookie names to be excluded. Names are case-sensitive.
-`query`: Use this property to exclude specific fields from the query string. The property's value is an array of field names from the query string to be excluded. Names are case-sensitive.
-`body-form`: Use this property to exclude specific fields from a request that uses the media type `application/x-www-form-urlencoded`. The property's value is an array of the field names from the body to be excluded. Names are case-sensitive.
-`body-json`: Use this property to exclude specific JSON nodes from a request that uses the media type `application/json`. The property's value is an array, each entry of the array is a [JSON Path](https://goessner.net/articles/JsonPath/) expression.
-`body-xml`: Use this property to exclude specific XML nodes from a request that uses media type `application/xml`. The property's value is an array, each entry of the array is a [XPath v2](https://www.w3.org/TR/xpath20/) expression.
To exclude the header `Upgrade-Insecure-Requests`, set the `header` property's value to an array with the header name: `[ "Upgrade-Insecure-Requests" ]`. For instance, the JSON document looks like this:
```json
{
"headers": [ "Upgrade-Insecure-Requests" ]
}
```
Header names are case-insensitive, thus the header name `UPGRADE-INSECURE-REQUESTS` is equivalent to `Upgrade-Insecure-Requests`.
##### Excluding both a header and two cookies
To exclude the header `Authorization` and the cookies `PHPSESSID` and `csrftoken`, set the `headers` property's value to an array with header name `[ "Authorization" ]` and the `cookies` property's value to an array with the cookies' names `[ "PHPSESSID", "csrftoken" ]`. For instance, the JSON document looks like this:
```json
{
"headers": [ "Authorization" ],
"cookies": [ "PHPSESSID", "csrftoken" ]
}
```
##### Excluding a `body-form` parameter
To exclude the `password` field in a request that uses `application/x-www-form-urlencoded`, set the `body-form` property's value to an array with the field name `[ "password" ]`. For instance, the JSON document looks like this:
```json
{
"body-form": [ "password" ]
}
```
The exclude parameters uses `body-form` when the request uses a content type `application/x-www-form-urlencoded`.
The JSON Path expression uses special syntax to identify JSON nodes: `$` refers to the root of the JSON document, `.` refers to the current object (in our case the root object), and the text `schema` refers to a property name. Thus, the JSON path expression `$.schema` refers to a property `schema` in the root object.
The exclude parameters uses `body-json` when the request uses a content type `application/json`. Each entry in `body-json` is expected to be a [JSON Path expression](https://goessner.net/articles/JsonPath/). In JSON Path, characters like `$`, `*`, `.` among others have special meaning.
To exclude the property `password` on each entry of an array of `users` at the root level, set the `body-json` property's value to an array with the JSON Path expression `[ "$.users[*].paswword" ]`.
The JSON Path expression starts with `$` to refer to the root node and uses `.` to refer to the current node. Then, it uses `users` to refer to a property and the characters `[` and `]` to enclose the index in the array you want to use, instead of providing a number as an index you use `*` to specify any index. After the index reference, we find `.` which now refers to any given selected index in the array, preceded by a property name `password`.
The exclude parameters uses `body-json` when the request uses a content type `application/json`. Each entry in `body-json` is expected to be a [JSON Path expression](https://goessner.net/articles/JsonPath/). In JSON Path characters like `$`, `*`, `.` among others have special meaning.
To exclude an attribute named `isEnabled` located in the root element `credentials`, set the `body-xml` property's value to an array with the XPath expression `[ "/credentials/@isEnabled" ]`.
The XPath expression `/credentials/@isEnabled`, starts with `/` to indicate the root of the XML document, then it is followed by the word `credentials` which indicates the name of the element to match. It uses a `/` to refer to a node of the previous XML element, and the character `@` to indicate that the name `isEnable` is an attribute.
The exclude parameters uses `body-xml` when the request uses a content type `application/xml`. Each entry in `body-xml` is expected to be an [XPath v2 expression](https://www.w3.org/TR/xpath20/). In XPath expressions, characters like `@`, `/`, `:`, `[`, `]` among others have special meanings.
To exclude the text of the `username` element contained in root node `credentials`, set the `body-xml` property's value to an array with the XPath expression `[/credentials/username/text()" ]`.
In the XPath expression `/credentials/username/text()`, the first character `/` refers to the root XML node, and then after it indicates an XML element's name `credentials`. Similarly, the character `/` refers to the current element, followed by a new XML element's name `username`. Last part has a `/` that refers to the current element, and uses a XPath function called `text()` which identifies the text of the current element.
The exclude parameters uses `body-xml` when the request uses a content type `application/xml`. Each entry in `body-xml` is expected to be a [XPath v2 expression](https://www.w3.org/TR/xpath20/). In XPath expressions characters like `@`, `/`, `:`, `[`, `]` among others have special meanings.
To exclude the element `username` contained in root node `credentials`, set the `body-xml` property's value to an array with the XPath expression `[/credentials/username" ]`.
In the XPath expression `/credentials/username`, the first character `/` refers to the root XML node, and then after it indicates an XML element's name `credentials`. Similarly, the character `/` refers to the current element, followed by a new XML element's name `username`.
The exclude parameters uses `body-xml` when the request uses a content type `application/xml`. Each entry in `body-xml` is expected to be a [XPath v2 expression](https://www.w3.org/TR/xpath20/). In XPath expressions characters like `@`, `/`, `:`, `[`, `]` among others have special meanings.
To exclude a XML element `login` which is defined in namespace `s`, and contained in `credentials` root node, set the `body-xml` property's value to an array with the XPath expression `[ "/credentials/s:login" ]`.
In the XPath expression `/credentials/s:login`, the first character `/` refers to the root XML node, and then after it indicates an XML element's name `credentials`. Similarly, the character `/` refers to the current element, followed by a new XML element's name `s:login`. Notice that name contains the character `:`, this character separates the namespace from the node name.
The namespace name should have been defined in the XML document which is part of the body request. You may check the namespace in the specification document HAR, OpenAPI, or Postman Collection file.
The exclude parameters uses `body-xml` when the request uses a content type `application/xml`. Each entry in `body-xml` is expected to be a [XPath v2 expression](https://www.w3.org/TR/xpath20/). In XPath expressions characters like `@`, `/`, `:`, `[`, `]` among others have special meanings.
To provide the exclusion JSON document set the variable `FUZZAPI_EXCLUDE_PARAMETER_ENV` with the JSON string. In the following example, the `.gitlab-ci.yml`, the `FUZZAPI_EXCLUDE_PARAMETER_ENV` variable is set to a JSON string:
To provide the exclusion JSON document, set the variable `FUZZAPI_EXCLUDE_PARAMETER_FILE` with the JSON file path. The file path is relative to the job current working directory. In the following example `.gitlab-ci.yml` file, the `FUZZAPI_EXCLUDE_PARAMETER_FILE` variable is set to a JSON file path:
The `api-fuzzing-exclude-parameters.json` is a JSON document that follows the structure of [exclude parameters document](#exclude-parameters-using-a-json-document).
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/357195) in GitLab 14.10.
As an alternative to excluding by paths, you can filter by any other component in the URL by using the `FUZZAPI_EXCLUDE_URLS` CI/CD variable. This variable can be set in your `.gitlab-ci.yml` file. The variable can store multiple values, separated by commas (`,`). Each value is a regular expression. Because each entry is a regular expression, an entry such as `.*` excludes all URLs because it is a regular expression that matches everything.
In your job output you can check if any URLs matched any provided regular expression from `FUZZAPI_EXCLUDE_URLS`. Matching operations are listed in the **Excluded Operations** section. Operations listed in the **Excluded Operations** should not be listed in the **Tested Operations** section. For example the following portion of a job output:
```plaintext
2021-05-27 21:51:08 [INF] API Security: --[ Tested Operations ]-------------------------
2021-05-27 21:51:08 [INF] API Security: 201 POST http://target:7777/api/users CREATED
2021-05-27 21:51:08 [INF] API Security: ------------------------------------------------
2021-05-27 21:51:08 [INF] API Security: --[ Excluded Operations ]-----------------------
2021-05-27 21:51:08 [INF] API Security: GET http://target:7777/api/messages
2021-05-27 21:51:08 [INF] API Security: POST http://target:7777/api/messages
2021-05-27 21:51:08 [INF] API Security: ------------------------------------------------
```
NOTE:
Each value in `FUZZAPI_EXCLUDE_URLS` is a regular expression. Characters such as `.` , `*` and `$` among many others have special meanings in [regular expressions](https://en.wikipedia.org/wiki/Regular_expression#Standards).
#### Examples
##### Excluding a URL and child resources
The following example excludes the URL `http://target/api/auth` and its child resources.
##### Excluding two URLs and allow their child resources
To exclude the URLs `http://target/api/buy` and `http://target/api/sell` but allowing to scan their child resources, for instance: `http://target/api/buy/toy` or `http://target/api/sell/chair`. You could use the value `http://target/api/buy/$,http://target/api/sell/$`. This value is using two regular expressions, each of them separated by a `,` character. Hence, it contains `http://target/api/buy$` and `http://target/api/sell$`. In each regular expression, the trailing `$` character points out where the matching URL should end.
##### Excluding two URLs and their child resources
In order to exclude the URLs: `http://target/api/buy` and `http://target/api/sell`, and their child resources. To provide multiple URLs we use the `,` character as follows:
In order to exclude exactly `https://target/api/v1/user/create` and `https://target/api/v2/user/create` or any other version (`v3`,`v4`, and more). We could use `https://target/api/v.*/user/create$`, in the previous regular expression `.` indicates any character and `*` indicates zero or more times, additionally `$` indicates that the URL should end there.
For self-managed GitLab instances in an environment with limited, restricted, or intermittent access to external resources through the internet, some adjustments are required for the Web API Fuzz testing job to successfully run.
Steps:
1. Host the Docker image in a local container registry.
1. Set the `SECURE_ANALYZERS_PREFIX` to the local container registry.
The Docker image for API Fuzzing must be pulled (downloaded) from the public registry and then pushed (imported) into a local registry. The GitLab container registry can be used to locally host the Docker image. This process can be performed using a special template. See [loading Docker images onto your offline host](../offline_deployments/index.md#loading-docker-images-onto-your-offline-host) for instructions.
Once the Docker image is hosted locally, the `SECURE_ANALYZERS_PREFIX` variable is set with the location of the local registry. The variable must be set such that concatenating `/api-security:2` results in a valid image location.
A bug exists in versions of the API Fuzzing analyzer prior to v1.6.196 that can cause a background process to fail under certain conditions. The solution is to update to a newer version of the API Fuzzing analyzer.
### `Failed to start session with scanner. Please retry, and if the problem persists reach out to support.`
The API Fuzzing engine outputs an error message when it cannot establish a connection with the scanner application component. The error message is shown in the job output window of the `apifuzzer_fuzz` job. A common cause for this issue is that the background component cannot use the selected port as it's already in use. This error can occur intermittently if timing plays a part (race condition). This issue occurs most often with Kubernetes environments when other services are mapped into the container causing port conflicts.
Before proceeding with a solution, it is important to confirm that the error message was produced because the port was already taken. To confirm this was the cause:
1. Go to the job console.
1. Look for the artifact `gl-api-security-scanner.log`. You can either download all artifacts by selecting **Download** and then search for the file, or directly start searching by selecting **Browse**.
1. Open the file `gl-api-security-scanner.log` in a text editor.
1. If the error message was produced because the port was already taken, you should see in the file a message like the following:
- In [GitLab 15.5 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/367734):
```log
Failed to bind to address http://127.0.0.1:5500: address already in use.
```
- In GitLab 15.4 and earlier:
```log
Failed to bind to address http://[::]:5000: address already in use.
```
The text `http://[::]:5000` in the previous message could be different in your case, for instance it could be `http://[::]:5500` or `http://127.0.0.1:5500`. As long as the remaining parts of the error message are the same, it is safe to assume the port was already taken.
If you did not find evidence that the port was already taken, check other troubleshooting sections which also address the same error message shown in the job console output. If there are no more options, feel free to [get support or request an improvement](#get-support-or-request-an-improvement) through the proper channels.
Once you have confirmed the issue was produced because the port was already taken. Then, [GitLab 15.5 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/367734) introduced the configuration variable `FUZZAPI_API_PORT`. This configuration variable allows setting a fixed port number for the scanner background component.
**Solution**
1. Ensure your `.gitlab-ci.yml` file defines the configuration variable `FUZZAPI_API_PORT`.
1. Update the value of `FUZZAPI_API_PORT` to any available port number greater than 1024. We recommend checking that the new value is not in used by GitLab. See the full list of ports used by GitLab in [Package defaults](../../../administration/package_information/defaults.md#ports)
At the start of an API Fuzzing job the OpenAPI Specification is validated against the [published schema](https://github.com/OAI/OpenAPI-Specification/tree/master/schemas). This error is shown when the provided OpenAPI Specification has validation errors. Errors can be introduced when creating an OpenAPI Specification manually, and also when the schema is generated.
- In [GitLab 13.11 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/323939), `Error, the OpenAPI document is not valid. Errors were found during validation of the document using the published OpenAPI schema`
1. Use the [Swagger Editor](https://editor.swagger.io/) to identify validation problems in your specification. The visual nature of the Swagger Editor makes it easier to understand what needs to change.
1. Alternatively, you can check the log output and look for schema validation warnings. They are prefixed with messages such as `OpenAPI 2.0 schema validation error` or `OpenAPI 3.0.x schema validation error`. Each failed validation provides extra information about `location` and `description`. Note that JSON Schema validation messages might not be easy to understand. This is why we recommend the use of editors to validate schema documents.
1. Review the documentation for the OpenAPI generation your framework/tech stack is using. Identify the changes needed to produce a correct OpenAPI document.
1. Once the validation issues are resolved, re-run your pipeline.
1. The simplest solution is to use a visual tool to edit and validate the OpenAPI document. For example the [Swagger Editor](https://editor.swagger.io/) highlights schema errors and possible solutions.

The API Fuzzing engine outputs an error message when it cannot establish a connection with the scanner application component. The error message is shown in the job output window of the `apifuzzer_fuzz` job. A common cause of this issue is changing the `FUZZAPI_API` variable from its default.
**Error message**
- In [GitLab 13.11 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/323939), `Failed to start scanner session (version header not found).`
- In GitLab 13.10 and earlier, `API Security version header not found. Are you sure that you are connecting to the API Security server?`.
- Remove the `FUZZAPI_API` variable from the `.gitlab-ci.yml` file. The value will be inherited from the API Fuzzing CI/CD template. We recommend this method instead of manually setting a value.
- If removing the variable is not possible, check to see if this value has changed in the latest version of the [API Fuzzing CI/CD template](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Security/API-Fuzzing.gitlab-ci.yml). If so, update the value in the `.gitlab-ci.yml` file.
The API Fuzzing analyzer outputs an error message when it cannot determine the target API after inspecting the OpenAPI document. This error message is shown when the target API has not been set in the `.gitlab-ci.yml`file, it is not available in the `environment_url.txt` file, and it could not be computed using the OpenAPI document.
There is an order of precedence in which the API Fuzzing analyzer tries to get the target API when checking the different sources. First, it will try to use the `FUZZAPI_TARGET_URL`. If the environment variable has not been set, then the API Fuzzing analyzer will attempt to use the `environment_url.txt` file. If there is no file `environment_url.txt`, the API Fuzzing analyzer will then use the OpenAPI document contents and the URL provided in `FUZZAPI_OPENAPI` (if a URL is provided) to try to compute the target API.
The best-suited solution will depend on whether or not your target API changes for each deployment. In static environments, the target API is the same for each deployment, in this case please refer to the [static environment solution](#static-environment-solution). If the target API changes for each deployment a [dynamic environment solution](#dynamic-environment-solutions) should be applied.
For environments where the target API remains the same, we recommend you specify the target URL by using the `FUZZAPI_TARGET_URL` environment variable. In your `.gitlab-ci.yml` file, add a variable `FUZZAPI_TARGET_URL`. The variable must be set to the base URL of API testing target. For example:
In a dynamic environment your target API changes for each different deployment. In this case, there is more than one possible solution, we recommend to use the `environment_url.txt` file when dealing with dynamic environments.
To support dynamic environments in which the target API URL changes during each pipeline, API Fuzzing supports the use of an `environment_url.txt` file that contains the URL to use. This file is not checked into the repository, instead it's created during the pipeline by the job that deploys the test target and collected as an artifact that can be used by later jobs in the pipeline. The job that creates the `environment_url.txt` file must run before the API Fuzzing job.
1. Modify the test target deployment job adding the base URL in an `environment_url.txt` file at the root of your project.
1. Modify the test target deployment job collecting the `environment_url.txt` as an artifact.
There are cases where the document is autogenerated with an invalid schema or cannot be edited manually in a timely manner. In those scenarios, the API Fuzzing is able to perform a relaxed validation by setting the variable `FUZZAPI_OPENAPI_RELAXED_VALIDATION`. We recommend providing a fully compliant OpenAPI document to prevent unexpected behaviors.
To detect and correct elements that don't comply with the OpenAPI specifications, we recommend using an editor. An editor commonly provides document validation, and suggestions to create a schema-compliant OpenAPI document. Suggested editors include:
If your OpenAPI document is generated manually, load your document in the editor and fix anything that is non-compliant. If your document is generated automatically, load it in your editor to identify the issues in the schema, then go to the application and perform the corrections based on the framework you are using.
#### Enable OpenAPI relaxed validation
Relaxed validation is meant for cases when the OpenAPI document cannot meet OpenAPI specifications, but it still has enough content to be consumed by different tools. A validation is performed but less strictly in regards to document schema.
API Fuzzing can still try to consume an OpenAPI document that does not fully comply with OpenAPI specifications. To instruct API Fuzzing analyzer to perform a relaxed validation, set the variable `FUZZAPI_OPENAPI_RELAXED_VALIDATION` to any value, for example:
API Fuzzing uses the specified media types in the OpenAPI document to generate requests. If no request can be created due to the lack of supported media types, then an error will be thrown.
- In [GitLab 14.10 and later](https://gitlab.com/gitlab-org/gitlab/-/issues/333304), `Error, no operation in the OpenApi document is consuming any supported media type. Check 'OpenAPI Specification' to check the supported media types.`
**Solution**
1. Review the supported media types in the [OpenAPI Specification](#openapi-specification) section.
1. Edit your OpenAPI document, allowing at least a given operation to accept any of the supported media types. Alternatively, a supported media type could be set in the OpenAPI document level and get applied to all operations. This step may require changes in your application to ensure the supported media type is accepted by the application.
