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.
### Enable Dependency Scanning via an automatic merge request
> - [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/4908) in GitLab 14.1.
> - [Deployed behind a feature flag](../../../user/feature_flags.md), enabled by default.
> - Enabled on GitLab.com.
> - Recommended for production use.
> - For GitLab self-managed instances, GitLab administrators can opt to [disable it](#enable-or-disable-configure-dependency-scanning-via-a-merge-request). **(ULTIMATE SELF)**
WARNING:
This feature might not be available to you. Check the **version history** note above for details.
There can be
[risks when disabling released features](../../../user/feature_flags.md#risks-when-disabling-released-features).
Refer to this feature's version history for more details.
To enable Dependency Scanning in a project, you can create a merge request
from the Security Configuration page.
1. In the project where you want to enable Dependency Scanning, navigate to
**Security & Compliance > Configuration**.
1. In the **Dependency Scanning** row, select **Configure via Merge Request**.
This automatically creates a merge request with the changes necessary to enable Dependency Scanning
that you can review and merge to complete the configuration.
| `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`. See [Using a custom SSL CA certificate authority](#using-a-custom-ssl-ca-certificate-authority) for more details. |
| `DS_EXCLUDED_ANALYZERS` | Specify the analyzers (by name) to exclude from Dependency Scanning. For more information, see [Dependency Scanning Analyzers](analyzers.md). |
| `DS_DEFAULT_ANALYZERS` | ([**DEPRECATED - use `DS_EXCLUDED_ANALYZERS` instead**](https://gitlab.com/gitlab-org/gitlab/-/issues/287691)) Override the names of the official default images. For more information, see [Dependency Scanning Analyzers](analyzers.md). |
| `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_ANALYZERS_PREFIX` | Override the name of the Docker registry providing the official default images (proxy). Read more about [customizing analyzers](analyzers.md). |
| `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`. |
| `BUNDLER_AUDIT_UPDATE_DISABLED` | `bundler-audit` | `"false"` | Disable automatic updates for the `bundler-audit` analyzer. Use 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`. |
| `GEMNASIUM_DB_LOCAL_PATH` | `gemnasium` | `/gemnasium-db` | Path to local Gemnasium database. |
| `DS_JAVA_VERSION` | `gemnasium-maven` | `11` | Version of Java. Available versions: `8`, `11`, `13`, `14`, `15`, `16`. Maven and Gradle use the Java version specified by this value (Dependency Scanning for Gradle does not currently support Java `16`). |
| `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-repositories). |
| `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`. |
| `PIP_INDEX_URL` | `gemnasium-python` | `https://pypi.org/simple` | Base URL of Python Package Index. |
| `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. **Warning:** Please read [the following security consideration](#python-projects) when using this environment variable. |
| `PIP_REQUIREMENTS_FILE` | `gemnasium-python` | | Pip requirements file to be scanned. |
| `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). |
| `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` 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` 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. |
You can use the `ADDITIONAL_CA_CERT_BUNDLE` CI/CD variable to configure a custom SSL CA certificate authority. The `ADDITIONAL_CA_CERT_BUNDLE` value should contain the [text representation of the X.509 PEM public-key certificate](https://tools.ietf.org/html/rfc7468#section-5.1). For example, to configure this value in the `.gitlab-ci.yml` file, use the following:
The `ADDITIONAL_CA_CERT_BUNDLE` value can also be configured as a [custom variable in the UI](../../../ci/variables/index.md#custom-cicd-variables), either as a `file`, which requires the path to the certificate, or as a variable, which requires the text representation of the 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` CI/CD variable to the URL of this repository. For more information on configuration variables, see [Dependency Scanning](#configuring-dependency-scanning).
- _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.
