The current detection logic limits the maximum search depth to two levels. For example, the `gemnasium-dependency_scanning` job is enabled if a repository contains either a `Gemfile` or `api/Gemfile` file, but not if the only supported dependency file is `api/client/Gemfile`.
The [Security Scanner Integration](../../../development/integrations/secure.md) documentation explains how to integrate other security scanners into GitLab.
| `SECURE_ANALYZERS_PREFIX` | Override the name of the Docker registry providing the official default images (proxy). Read more about [customizing analyzers](analyzers.md). |
| `ADDITIONAL_CA_CERT_BUNDLE` | Bundle of CA certs to trust. The bundle of certificates provided here is also used by other tools during the scanning process, such as `git`, `yarn`, or `npm`. |
| `DS_EXCLUDED_PATHS` | Exclude vulnerabilities from output based on the paths. A comma-separated list of patterns. Patterns can be globs, or file or folder paths (for example, `doc,spec`). Parent directories also match patterns. Default: `"spec, test, tests, tmp"` |
| `SECURE_LOG_LEVEL` | Set the minimum logging level. Messages of this logging level or higher are output. From highest to lowest severity, the logging levels are: `fatal`, `error`, `warn`, `info`, `debug`. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/10880) in GitLab 13.1. Default: `info` |
| `PIP_EXTRA_INDEX_URL` | `gemnasium-python` | | 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. |
| `DS_PIP_VERSION` | `gemnasium-python` | | Force the install of a specific pip version (example: `"19.3"`), otherwise the pip installed in the Docker image is used. ([Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12811) in GitLab 12.7) |
| `DS_PIP_DEPENDENCY_PATH` | `gemnasium-python` | | Path to load Python pip dependencies from. ([Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/12412) in GitLab 12.2) |
| `DS_PYTHON_VERSION` | `retire.js` | | 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/-/issues/12296) in GitLab 12.1, [removed](https://www.python.org/doc/sunset-python-2/) in GitLab 13.7)|
| `DS_JAVA_VERSION` | `gemnasium-maven` | `11` | Version of Java. Available versions: `8`, `11`, `13`, `14`. Maven and Gradle use the Java version specified by this value. |
| `MAVEN_CLI_OPTS` | `gemnasium-maven` | `"-DskipTests --batch-mode"` | List of command line arguments that are passed to `maven` by the analyzer. See an example for [using private repositories](../index.md#using-private-maven-repos). |
| `GRADLE_CLI_OPTS` | `gemnasium-maven` | | List of command line arguments that are passed to `gradle` by the analyzer. |
| `SBT_CLI_OPTS` | `gemnasium-maven` | | List of command-line arguments that the analyzer passes to `sbt`. |
| `BUNDLER_AUDIT_UPDATE_DISABLED` | `bundler-audit` | `"false"` | Disable automatic updates for the `bundler-audit` analyzer. Useful if you're running dependency scanning in an offline, air-gapped environment.|
| `BUNDLER_AUDIT_ADVISORY_DB_URL` | `bundler-audit` | `https://github.com/rubysec/ruby-advisory-db` | URL of the advisory database used by bundler-audit. |
| `BUNDLER_AUDIT_ADVISORY_DB_REF_NAME` | `bundler-audit` | `master` | Git ref for the advisory database specified by `BUNDLER_AUDIT_ADVISORY_DB_URL`. |
| `RETIREJS_JS_ADVISORY_DB` | `retire.js` | `https://raw.githubusercontent.com/RetireJS/retire.js/master/repository/jsrepository.json` | Path or URL to `retire.js` JS vulnerability data file. Note that if the URL hosting the data file uses a custom SSL certificate, for example in an offline installation, you can pass the certificate in the `ADDITIONAL_CA_CERT_BUNDLE` environment variable. |
| `RETIREJS_NODE_ADVISORY_DB` | `retire.js` | `https://raw.githubusercontent.com/RetireJS/retire.js/master/repository/npmrepository.json` | Path or URL to `retire.js` node vulnerability data file. Note that if the URL hosting the data file uses a custom SSL certificate, for example in an offline installation, you can pass the certificate in the `ADDITIONAL_CA_CERT_BUNDLE` environment variable. |
| `RETIREJS_ADVISORY_DB_INSECURE` | `retire.js` | `false` | Enable fetching remote JS and Node vulnerability data files (defined by the `RETIREJS_JS_ADVISORY_DB` and `RETIREJS_NODE_ADVISORY_DB` variables) from hosts using an insecure or self-signed SSL (TLS) certificate. |

"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.",
"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.",
- Docker Container Registry with locally available copies of dependency scanning [analyzer](https://gitlab.com/gitlab-org/security-products/analyzers) images.
- If you have a limited access environment you need to allow access, such as using a proxy, to the advisory database: `https://gitlab.com/gitlab-org/security-products/gemnasium-db.git`.
If you are unable to permit access to `https://gitlab.com/gitlab-org/security-products/gemnasium-db.git` you must host an offline copy of this `git` repository and set the `GEMNASIUM_DB_REMOTE_URL` variable to the URL of this repository. For more information on configuration variables, see [Dependency Scanning](#configuring-dependency-scanning).
- _Only if scanning Ruby projects_: Host an offline Git copy of the [advisory database](https://github.com/rubysec/ruby-advisory-db).
- _Only if scanning npm/yarn projects_: Host an offline copy of the [retire.js](https://github.com/RetireJS/retire.js/) [node](https://github.com/RetireJS/retire.js/blob/master/repository/npmrepository.json) and [js](https://github.com/RetireJS/retire.js/blob/master/repository/jsrepository.json) advisory databases.
meaning the runner tries to pull Docker images from the GitLab container registry even if a local
copy is available. The GitLab Runner [`pull_policy` can be set to `if-not-present`](https://docs.gitlab.com/runner/executors/docker.html#using-the-if-not-present-pull-policy)
[`docker export`](https://docs.docker.com/engine/reference/commandline/export/), and [`docker import`](https://docs.docker.com/engine/reference/commandline/import/).
### Getting warning message `gl-dependency-scanning-report.json: no matching files`
For information on this, see the [general Application Security troubleshooting section](../../../ci/pipelines/job_artifacts.md#error-message-no-files-to-upload).
### Limitation when using rules:exists
The [dependency scanning CI template](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Security/Dependency-Scanning.gitlab-ci.yml)
uses the [`rules:exists`](../../../ci/yaml/README.md#rulesexists)
syntax. This directive is limited to 10000 checks and always returns `true` after reaching this
number. Because of this, and depending on the number of files in your repository, a dependency
scanning job might be triggered even if the scanner doesn't support your project.
### Issues building projects with npm or yarn packages relying on Python 2
Python 2 was removed (see: [Python 2 sunsetting](https://www.python.org/doc/sunset-python-2/)) from the `retire.js` analyzer in GitLab 13.7 (analyzer version 2.10.1). Projects using packages
with a dependency on this version of Python should use `retire.js` version 2.10.0 or lower (for example, `registry.gitlab.com/gitlab-org/security-products/analyzers/retire.js:2.10.0`).
