Dependency Scanning can be [configured](#customizing-the-dependency-scanning-settings)
using environment variables.
| Environment variable | Function |
|-------------------------------- |----------|
| `DS_ANALYZER_IMAGES` | Comma separated list of custom images. The official default images are still enabled. Read more about [customizing analyzers](analyzers.md). |
| `DS_ANALYZER_IMAGE_PREFIX` | Override the name of the Docker registry providing the official default images (proxy). Read more about [customizing analyzers](analyzers.md). |
| `DS_ANALYZER_IMAGE_TAG` | Override the Docker tag of the official default images. Read more about [customizing analyzers](analyzers.md). |
| `DS_PYTHON_VERSION` | Version of Python. If set to 2, dependencies are installed using Python 2.7 instead of Python 3.6. ([Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/12296) in GitLab 12.1)|
| `DS_DEFAULT_ANALYZERS` | Override the names of the official default images. Read more about [customizing analyzers](analyzers.md). |
| `DS_DISABLE_REMOTE_CHECKS` | Do not send any data to GitLab. Used in the [Gemnasium analyzer](#remote-checks). |
| `DS_PULL_ANALYZER_IMAGES` | Pull the images from the Docker registry (set to `0` to disable). |
| `DS_EXCLUDED_PATHS` | Exclude vulnerabilities from output based on the paths. A comma-separated list of patterns. Patterns can be globs, file or folder paths. Parent directories will also match patterns. |
| `DS_DOCKER_CLIENT_NEGOTIATION_TIMEOUT` | Time limit for Docker client negotiation. Timeouts are parsed using Go's [`ParseDuration`](https://golang.org/pkg/time/#ParseDuration). Valid time units are `ns`, `us` (or `µs`), `ms`, `s`, `m`, `h`. For example, `300ms`, `1.5h`, or `2h45m`. |
| `DS_PULL_ANALYZER_IMAGE_TIMEOUT` | Time limit when pulling the image of an analyzer. Timeouts are parsed using Go's [`ParseDuration`](https://golang.org/pkg/time/#ParseDuration). Valid time units are `ns`, `us` (or `µs`), `ms`, `s`, `m`, `h`. For example, `300ms`, `1.5h`, or `2h45m`. |
| `DS_RUN_ANALYZER_TIMEOUT` | Time limit when running an analyzer. Timeouts are parsed using Go's [`ParseDuration`](https://golang.org/pkg/time/#ParseDuration). Valid time units are `ns`, `us` (or `µs`), `ms`, `s`, `m`, `h`. For example, `300ms`, `1.5h`, or `2h45m`. |
| `PIP_INDEX_URL` | Base URL of Python Package Index (default https://pypi.org/simple). |
| `PIP_EXTRA_INDEX_URL` | Array of [extra URLs](https://pip.pypa.io/en/stable/reference/pip_install/#cmdoption-extra-index-url) of package indexes to use in addition to `PIP_INDEX_URL`. Comma separated. |
The JSON report artifacts are not a public API of Dependency Scanning and their format may change in future.
The Dependency Scanning tool emits a JSON report file. Here is an example of the report structure with all important parts of
it highlighted:
```json-doc
{
"version": "2.0",
"vulnerabilities": [
{
"category": "dependency_scanning",
"name": "Regular Expression Denial of Service",
"message": "Regular Expression Denial of Service in debug",
"description": "The debug module is vulnerable to regular expression denial of service when untrusted user input is passed into the `o` formatter. It takes around 50k characters to block for 2 seconds making this a low severity issue.",
"name": "Authentication bypass via incorrect DOM traversal and canonicalization",
"message": "Authentication bypass via incorrect DOM traversal and canonicalization in saml2-js",
"description": "Some XML DOM traversal and canonicalization APIs may be inconsistent in handling of comments within XML nodes. Incorrect use of these APIs by some SAML libraries results in incorrect parsing of the inner text of XML nodes such that any inner text after the comment is lost prior to cryptographically signing the SAML message. Text after the comment therefore has no impact on the signature on the SAML message.\r\n\r\nA remote attacker can modify SAML content for a SAML service provider without invalidating the cryptographic signature, which may allow attackers to bypass primary authentication for the affected SAML service provider.",
| `version` | Report syntax version used to generate this JSON. |
| `vulnerabilities` | Array of vulnerability objects. |
| `vulnerabilities[].category` | Where this vulnerability belongs (SAST, Dependency Scanning etc.). For Dependency Scanning, it will always be `dependency_scanning`. |
| `vulnerabilities[].name` | Name of the vulnerability, this must not include the occurrence's specific information. Optional. |
| `vulnerabilities[].message` | A short text that describes the vulnerability, it may include occurrence's specific information. Optional. |
| `vulnerabilities[].description` | A long text that describes the vulnerability. Optional. |
| `vulnerabilities[].cve` | A fingerprint string value that represents a concrete occurrence of the vulnerability. It's used to determine whether two vulnerability occurrences are same or different. May not be 100% accurate. **This is NOT a [CVE](https://cve.mitre.org/)**. |
| `vulnerabilities[].severity` | How much the vulnerability impacts the software. Possible values: `Undefined` (an analyzer has not provided this info), `Info`, `Unknown`, `Low`, `Medium`, `High`, `Critical`. |
| `vulnerabilities[].confidence` | How reliable the vulnerability's assessment is. Possible values: `Undefined` (an analyzer has not provided this info), `Ignore`, `Unknown`, `Experimental`, `Low`, `Medium`, `High`, `Confirmed`. |
| `vulnerabilities[].solution` | Explanation of how to fix the vulnerability. Optional. |
| `vulnerabilities[].scanner` | A node that describes the analyzer used to find this vulnerability. |
| `vulnerabilities[].scanner.id` | Id of the scanner as a snake_case string. |
| `vulnerabilities[].scanner.name` | Name of the scanner, for display purposes. |
| `vulnerabilities[].location` | A node that tells where the vulnerability is located. |
| `vulnerabilities[].location.file` | Path to the dependencies file (e.g., `yarn.lock`). Optional. |
| `vulnerabilities[].location.dependency` | A node that describes the dependency of a project where the vulnerability is located. |
| `vulnerabilities[].location.dependency.package` | A node that provides the information on the package where the vulnerability is located. |
| `vulnerabilities[].location.dependency.package.name` | Name of the package where the vulnerability is located. Optional. |
| `vulnerabilities[].location.dependency.version` | Version of the vulnerable package. Optional. |
| `vulnerabilities[].identifiers` | An ordered array of references that identify a vulnerability on internal or external DBs. |
| `vulnerabilities[].identifiers[].type` | Type of the identifier. Possible values: common identifier types (among `cve`, `cwe`, `osvdb`, and `usn`) or analyzer-dependent ones (e.g. `gemnasium` for [Gemnasium](https://gitlab.com/gitlab-org/security-products/analyzers/gemnasium/)). |
| `vulnerabilities[].identifiers[].name` | Name of the identifier for display purpose. |
| `vulnerabilities[].identifiers[].value` | Value of the identifier for matching purpose. |
| `vulnerabilities[].identifiers[].url` | URL to identifier's documentation. Optional. |
| `vulnerabilities[].links` | An array of references to external documentation pieces or articles that describe the vulnerability further. Optional. |
| `vulnerabilities[].links[].name` | Name of the vulnerability details link. Optional. |
| `vulnerabilities[].links[].url` | URL of the vulnerability details document. Optional. |
| `remediations` | An array of objects containing information on cured vulnerabilities along with patch diffs to apply. Empty if no remediations provided by an underlying analyzer. |
| `remediations[].fixes` | An array of strings that represent references to vulnerabilities fixed by this particular remediation. |
| `remediations[].fixes[].cve` | A string value that describes a fixed vulnerability occurrence in the same format as `vulnerabilities[].cve`. |
| `remediations[].summary` | Overview of how the vulnerabilities have been fixed. |
