Static Application Security Testing (SAST) (FREE)

Introduced in GitLab Ultimate 10.3.

All open source (OSS) analyzers were moved to GitLab Free in GitLab 13.3.

NOTE: The whitepaper "A Seismic Shift in Application Security" explains how 4 of the top 6 attacks were application based. Download it to learn how to protect your organization.

If you're using GitLab CI/CD, you can use Static Application Security Testing (SAST) to check your source code for known vulnerabilities. When a pipeline completes, the results of the SAST analysis are processed and shown in the pipeline's Security tab. If the pipeline is associated with a merge request, the SAST analysis is compared with the results of the target branch's analysis (if available). The results of that comparison are shown in the merge request. (ULTIMATE) If the pipeline is running from the default branch, the results of the SAST analysis are available in the security dashboards.

The results are sorted by the priority of the vulnerability:

Critical
High
Medium
Low
Info
Unknown

A pipeline consists of multiple jobs, including SAST and DAST scanning. If any job fails to finish for any reason, the security dashboard does not show SAST scanner output. For example, if the SAST job finishes but the DAST job fails, the security dashboard does not show SAST results. On failure, the analyzer outputs an exit code.

Use cases

Your code has a potentially dangerous attribute in a class, or unsafe code that can lead to unintended code execution.
Your application is vulnerable to cross-site scripting (XSS) attacks that can be leveraged to unauthorized access to session data.

Requirements

To run SAST jobs, by default, you need GitLab Runner with the docker or kubernetes executor. If you're using the shared runners on GitLab.com, this is enabled by default.

WARNING: Our SAST jobs require a Linux container type. Windows containers are not yet supported.

WARNING: If you use your own runners, make sure the Docker version installed is not 19.03.0. See troubleshooting information for details.

Supported languages and frameworks

GitLab SAST supports a variety of languages, package managers, and frameworks. Our SAST security scanners also feature automatic language detection which works even for mixed-language projects. If any supported language is detected in project source code we automatically run the appropriate SAST analyzers.

You can also view our language roadmap and request other language support by opening an issue.

Multi-project support

Introduced in GitLab 13.7.

GitLab SAST can scan repositories that contain multiple projects.

The following analyzers have multi-project support:

Bandit
ESLint
Gosec
Kubesec
NodeJsScan
MobSF
PMD
Security Code Scan
Semgrep
SpotBugs
Sobelow

Enable multi-project support for Security Code Scan

Multi-project support in the Security Code Scan requires a Solution (.sln) file in the root of the repository. For details on the Solution format, see the Microsoft reference Solution (.sln) file.

Contribute your scanner

The Security Scanner Integration documentation explains how to integrate other security scanners into GitLab.

Configuration

To configure SAST for a project you can:

Use Auto SAST, provided by Auto DevOps.
Configure SAST manually.
Configure SAST using the UI (introduced in GitLab 13.3).

Configure SAST manually

For GitLab 11.9 and later, to enable SAST you must include the SAST.gitlab-ci.yml template provided as a part of your GitLab installation. For GitLab versions earlier than 11.9, you can copy and use the job as defined that template.

Add the following to your .gitlab-ci.yml file:

include:
  - template: Security/SAST.gitlab-ci.yml

The included template creates SAST jobs in your CI/CD pipeline and scans your project's source code for possible vulnerabilities.

The results are saved as a SAST report artifact that you can later download and analyze. Due to implementation limitations, we always take the latest SAST artifact available.

Configure SAST in the UI

You can enable and configure SAST in the UI, either with default settings, or with customizations. Use the method that best meets your needs.

Configure SAST in the UI with default settings
Configure SAST in the UI with customizations

Configure SAST in the UI with default settings (FREE)

Introduced in GitLab 13.9

To enable and configure SAST with default settings:

On the top bar, select Menu > Projects and find your project.
On the left sidebar, select Security & Compliance > Configuration.
In the SAST section, select Enable via MR.
Review the draft MR that enables SAST with the default recommended settings in the .gitlab-ci.yml file.
Merge the MR to enable SAST. You should see SAST jobs run in that MR's pipeline.

NOTE: The configuration tool works best with no existing .gitlab-ci.yml file, or with a minimal configuration file. If you have a complex GitLab configuration file it may not be parsed successfully, and an error may occur.

Configure SAST in the UI with customizations (ULTIMATE)

Introduced in GitLab Ultimate 13.3.

Improved in GitLab Ultimate 13.4.

Improved in GitLab Ultimate 13.5.

To enable and configure SAST with customizations:

On the top bar, select Menu > Projects and find your project.
On the left sidebar, select Security & Compliance > Configuration.
If the project does not have a .gitlab-ci.yml file, select Enable in the Static Application Security Testing (SAST) row, otherwise select Configure.
Enter the custom SAST values.

Custom values are stored in the .gitlab-ci.yml file. For CI/CD variables not in the SAST Configuration page, their values are left unchanged. Default values are inherited from the GitLab SAST template.
Optionally, expand the SAST analyzers section, select individual SAST analyzers and enter custom analyzer values.
Select Create Merge Request.
Review and merge the merge request.

Customizing the SAST settings

The SAST settings can be changed through CI/CD variables by using the variables parameter in .gitlab-ci.yml. In the following example, we include the SAST template and at the same time we set the SAST_GOSEC_LEVEL variable to 2:

include:
  - template: Security/SAST.gitlab-ci.yml

variables:
  SAST_GOSEC_LEVEL: 2

Because the template is evaluated before the pipeline configuration, the last mention of the variable takes precedence.

Overriding SAST jobs

WARNING: Beginning in GitLab 13.0, the use of only and except is no longer supported. When overriding the template, you must use rules instead.

To override a job definition, (for example, change properties like variables or dependencies), declare a job with the same name as the SAST job to override. Place this new job after the template inclusion and specify any additional keys under it. For example, this enables FAIL_NEVER for the spotbugs analyzer:

include:
  - template: Security/SAST.gitlab-ci.yml

spotbugs-sast:
  variables:
    FAIL_NEVER: 1

Pinning to minor image version

While our templates use MAJOR version pinning to always ensure the latest analyzer versions are pulled, there are certain cases where it can be beneficial to pin an analyzer to a specific release. To do so, override the SAST_ANALYZER_IMAGE_TAG CI/CD variable in the job template directly.

In the example below, we pin to a specific patch version of the spotbugs analyzer and minor version of the semgrep analyzer:

include:
  - template: Security/SAST.gitlab-ci.yml

semgrep-sast:
  variables:
    SAST_ANALYZER_IMAGE_TAG: "2.12"

spotbugs-sast:
  variables:
    SAST_ANALYZER_IMAGE_TAG: "2.28.1"

Customize rulesets (ULTIMATE)

Introduced in GitLab 13.5.

You can customize the default scanning rules provided by our SAST analyzers.

Ruleset customization supports two capabilities:

Disabling predefined rules (available for all analyzers).
Modifying the default behavior of a given analyzer (only available for nodejs-scan and gosec).

These capabilities can be used simultaneously.

To customize the default scanning rules, create a file containing custom rules. These rules are passed through to the analyzer's underlying scanner tools.

To create a custom ruleset:

Create a .gitlab directory at the root of your project, if one doesn't already exist.
Create a custom ruleset file named sast-ruleset.toml in the .gitlab directory.

In the sast-ruleset.toml file, do one of the following:

Disable predefined rules belonging to SAST analyzers. In this example, the three disabled rules belong to eslint and sobelow by matching the corresponding identifiers' type and value:

[eslint]
  [[eslint.ruleset]]
    disable = true
    [eslint.ruleset.identifier]
      type = "eslint_rule_id"
      value = "security/detect-object-injection"

  [[eslint.ruleset]]
    disable = true
    [eslint.ruleset.identifier]
      type = "cwe"
      value = "185"

[sobelow]
  [[sobelow.ruleset]]
    disable = true
    [sobelow.ruleset.identifier]
      type = "sobelow_rule_id"
      value = "sql_injection"

Define a custom analyzer configuration. In this example, customized rules are defined for the nodejs-scan scanner:

[nodejs-scan]
  description = 'custom ruleset for nodejs-scan'

  [[nodejs-scan.passthrough]]
    type  = "raw"
    value = '''
- nodejs-extensions:
  - .js

  template-extensions:
  - .new
  - .hbs
  - ''

  ignore-filenames:
- skip.js

  ignore-paths:
  - __MACOSX
  - skip_dir
  - node_modules

  ignore-extensions:
  - .hbs

  ignore-rules:
  - regex_injection_dos
  - pug_jade_template
  - express_xss

'''

Provide the name of the file containing a custom analyzer configuration. In this example, customized rules for the gosec scanner are contained in the file gosec-config.json:
```
[gosec]
  description = 'custom ruleset for gosec'

  [[gosec.passthrough]]
    type  = "file"
    value = "gosec-config.json"
```

False Positive Detection (ULTIMATE)

Introduced in GitLab 14.2.

Vulnerabilities that have been detected and are false positives will be flagged as false positives in the security dashboard.

Using CI/CD variables to pass credentials for private repositories

Some analyzers require downloading the project's dependencies in order to perform the analysis. In turn, such dependencies may live in private Git repositories and thus require credentials like username and password to download them. Depending on the analyzer, such credentials can be provided to it via custom CI/CD variables.

Using a CI/CD variable to pass username and password to a private Maven repository

If your private Maven repository requires login credentials, you can use the MAVEN_CLI_OPTS CI/CD variable.

Enabling Kubesec analyzer

Introduced in GitLab Ultimate 12.6.

You need to set SCAN_KUBERNETES_MANIFESTS to "true" to enable the Kubesec analyzer. In .gitlab-ci.yml, define:

include:
  - template: Security/SAST.gitlab-ci.yml

variables:
  SCAN_KUBERNETES_MANIFESTS: "true"

Pre-compilation

If your project requires custom build configurations, it can be preferable to avoid compilation during your SAST execution and instead pass all job artifacts from an earlier stage in the pipeline. This is the current strategy when requiring a before_script execution to prepare your scan job.

To pass your project's dependencies as artifacts, the dependencies must be included in the project's working directory and specified using the artifacts:path configuration. If all dependencies are present, the COMPILE=false CI/CD variable can be provided to the analyzer and compilation is skipped:

stages:
  - build
  - test

include:
  - template: Security/SAST.gitlab-ci.yml

build:
  image: maven:3.6-jdk-8-slim
  stage: build
  script:
    - mvn package -Dmaven.repo.local=./.m2/repository
  artifacts:
    paths:
      - .m2/
      - target/

spotbugs-sast:
  dependencies:
    - build
  variables:
    MAVEN_REPO_PATH: ./.m2/repository
    COMPILE: "false"
  artifacts:
    reports:
      sast: gl-sast-report.json

To allow the analyzer to recognize the compiled artifacts, you must explicitly specify the path to the vendored directory. This configuration can vary per analyzer but in the case of Java above, you can use MAVEN_REPO_PATH. See Analyzer settings for the complete list of available options.

Available CI/CD variables

SAST can be configured using CI/CD variables.

Logging level

Introduced in GitLab 13.1.

To control the verbosity of logs, set the SECURE_LOG_LEVEL environment variable. Messages of this logging level or higher are output.

From highest to lowest severity, the logging levels are:

fatal
error
warn
info (default)
debug

Custom Certificate Authority

To trust a custom Certificate Authority, set the ADDITIONAL_CA_CERT_BUNDLE variable to the bundle of CA certs that you want to trust in the SAST environment. The ADDITIONAL_CA_CERT_BUNDLE value should contain the text representation of the X.509 PEM public-key certificate. For example, to configure this value in the .gitlab-ci.yml file, use the following:

variables:
  ADDITIONAL_CA_CERT_BUNDLE: |
      -----BEGIN CERTIFICATE-----
      MIIGqTCCBJGgAwIBAgIQI7AVxxVwg2kch4d56XNdDjANBgkqhkiG9w0BAQsFADCB
      ...
      jWgmPqF3vUbZE0EyScetPJquRFRKIesyJuBFMAs=
      -----END CERTIFICATE-----

The ADDITIONAL_CA_CERT_BUNDLE value can also be configured as a custom variable in the UI, either as a file, which requires the path to the certificate, or as a variable, which requires the text representation of the certificate.

Docker images

The following are Docker image-related CI/CD variables.

CI/CD variable	Description
`SECURE_ANALYZERS_PREFIX`	Override the name of the Docker registry providing the default images (proxy). Read more about customizing analyzers.
`SAST_EXCLUDED_ANALYZERS`	Names of default images that should never run. Read more about customizing analyzers.
`SAST_ANALYZER_IMAGE_TAG`	Override the default version of analyzer image. Read more about pinning the analyzer image version.

Vulnerability filters

Some analyzers make it possible to filter out vulnerabilities under a given threshold.

CI/CD variable	Default value	Description
`SAST_EXCLUDED_PATHS`	`spec, test, tests, tmp`	Exclude vulnerabilities from output based on the paths. This is a comma-separated list of patterns. Patterns can be globs, or file or folder paths (for example, `doc,spec`). Parent directories also match patterns. You might need to exclude temporary directories used by your build tool as these can generate false positives. To exclude paths, copy and paste the default excluded paths, then add your own paths to be excluded. If you don't specify the default excluded paths, you will override the defaults and only paths you specify will be excluded from the SAST scans.
`SEARCH_MAX_DEPTH`	4	SAST searches the repository to detect the programming languages used, and selects the matching analyzers. Set the value of `SEARCH_MAX_DEPTH` to specify how many directory levels the search phase should span. After the analyzers have been selected, the entire repository is analyzed.
`SAST_BANDIT_EXCLUDED_PATHS`		Comma-separated list of paths to exclude from scan. Uses Python's `fnmatch` syntax; For example: `'/tests/, /venv/'`
`SAST_BRAKEMAN_LEVEL`	1	Ignore Brakeman vulnerabilities under given confidence level. Integer, 1=Low 3=High.
`SAST_FLAWFINDER_LEVEL`	1	Ignore Flawfinder vulnerabilities under given risk level. Integer, 0=No risk, 5=High risk.
`SAST_GOSEC_LEVEL`	0	Ignore Gosec vulnerabilities under given confidence level. Integer, 0=Undefined, 1=Low, 2=Medium, 3=High.

Analyzer settings

Some analyzers can be customized with CI/CD variables.

CI/CD variable	Analyzer	Description
`SCAN_KUBERNETES_MANIFESTS`	Kubesec	Set to `"true"` to scan Kubernetes manifests.
`KUBESEC_HELM_CHARTS_PATH`	Kubesec	Optional path to Helm charts that `helm` uses to generate a Kubernetes manifest that `kubesec` scans. If dependencies are defined, `helm dependency build` should be ran in a `before_script` to fetch the necessary dependencies.
`KUBESEC_HELM_OPTIONS`	Kubesec	Additional arguments for the `helm` executable.
`COMPILE`	Gosec, SpotBugs	Set to `false` to disable project compilation and dependency fetching. Introduced for `SpotBugs` analyzer in GitLab 13.1 and `Gosec` analyzer in GitLab 14.0.
`ANT_HOME`	SpotBugs	The `ANT_HOME` variable.
`ANT_PATH`	SpotBugs	Path to the `ant` executable.
`GRADLE_PATH`	SpotBugs	Path to the `gradle` executable.
`JAVA_OPTS`	SpotBugs	Additional arguments for the `java` executable.
`JAVA_PATH`	SpotBugs	Path to the `java` executable.
`SAST_JAVA_VERSION`	SpotBugs	Which Java version to use. Supported versions are `8` and `11`. Defaults to `8`.
`MAVEN_CLI_OPTS`	SpotBugs	Additional arguments for the `mvn` or `mvnw` executable.
`MAVEN_PATH`	SpotBugs	Path to the `mvn` executable.
`MAVEN_REPO_PATH`	SpotBugs	Path to the Maven local repository (shortcut for the `maven.repo.local` property).
`SBT_PATH`	SpotBugs	Path to the `sbt` executable.
`FAIL_NEVER`	SpotBugs	Set to `1` to ignore compilation failure.
`SAST_GOSEC_CONFIG`	Gosec	{warning} Removed in GitLab 14.0 - use custom rulesets instead. Path to configuration for Gosec (optional).
`PHPCS_SECURITY_AUDIT_PHP_EXTENSIONS`	phpcs-security-audit	Comma separated list of additional PHP Extensions.
`SAST_DISABLE_BABEL`	NodeJsScan	{warning} Removed in GitLab 13.5
`SAST_SEMGREP_METRICS`	Semgrep	Set to `"false"` to disable sending anonymized scan metrics to r2c. Default: `true`. Introduced in GitLab 14.0.

Custom CI/CD variables

Introduced in GitLab Ultimate 12.5.

In addition to the aforementioned SAST configuration CI/CD variables, all custom variables are propagated to the underlying SAST analyzer images if the SAST vendored template is used.

NOTE: In GitLab 13.3 and earlier, variables whose names started with the following prefixes are not propagated to either the analyzer containers or SAST Docker container: DOCKER_, CI, GITLAB_, FF_, HOME, PWD, OLDPWD, PATH, SHLVL, HOSTNAME.

Experimental features

You can receive early access to experimental features. Experimental features might be added, removed, or promoted to regular features at any time.

Experimental features available are:

Enable scanning of iOS and Android apps using the MobSF analyzer.

Enable experimental features

To enable experimental features, add the following to your .gitlab-ci.yml file:

include:
  - template: Security/SAST.gitlab-ci.yml

variables:
  SAST_EXPERIMENTAL_FEATURES: "true"

Reports JSON format

The SAST tool emits a JSON report file. For more information, see the schema for this report.

The JSON report file can be downloaded from the CI pipelines page, or the pipelines tab on merge requests by setting artifacts: paths to gl-sast-report.json. For more information see Downloading artifacts.

Running SAST in an offline environment

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 SAST job to run successfully. For more information, see Offline environments.

Requirements for offline SAST

To use SAST in an offline environment, you need:

GitLab Runner with the docker or kubernetes executor.
A Docker Container Registry with locally available copies of SAST analyzer images.
Configure certificate checking of packages (optional).

GitLab Runner has a default pull policy of always, 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 in an offline environment if you prefer using only locally available Docker images. However, we recommend keeping the pull policy setting to always if not in an offline environment, as this enables the use of updated scanners in your CI/CD pipelines.

Make GitLab SAST analyzer images available inside your Docker registry

For SAST with all supported languages and frameworks, import the following default SAST analyzer images from registry.gitlab.com into your local Docker container registry:

registry.gitlab.com/security-products/sast/bandit:2
registry.gitlab.com/security-products/sast/brakeman:2
registry.gitlab.com/security-products/sast/eslint:2
registry.gitlab.com/security-products/sast/flawfinder:2
registry.gitlab.com/security-products/sast/gosec:3
registry.gitlab.com/security-products/sast/kubesec:2
registry.gitlab.com/security-products/sast/nodejs-scan:2
registry.gitlab.com/security-products/sast/phpcs-security-audit:2
registry.gitlab.com/security-products/sast/pmd-apex:2
registry.gitlab.com/security-products/sast/security-code-scan:2
registry.gitlab.com/security-products/sast/semgrep:2
registry.gitlab.com/security-products/sast/sobelow:2
registry.gitlab.com/security-products/sast/spotbugs:2

The process for importing Docker images into a local offline Docker registry depends on your network security policy. Please consult your IT staff to find an accepted and approved process by which external resources can be imported or temporarily accessed. These scanners are periodically updated with new definitions, and you may be able to make occasional updates on your own.

For details on saving and transporting Docker images as a file, see Docker's documentation on docker save, docker load, docker export, and docker import.

If support for Custom Certificate Authorities are needed

Support for custom certificate authorities was introduced in the following versions.

Analyzer	Version
`bandit`	v2.3.0
`brakeman`	v2.1.0
`eslint`	v2.9.2
`flawfinder`	v2.3.0
`gosec`	v2.5.0
`kubesec`	v2.1.0
`nodejs-scan`	v2.9.5
`phpcs-security-audit`	v2.8.2
`pmd-apex`	v2.1.0
`security-code-scan`	v2.7.3
`semgrep`	v0.0.1
`sobelow`	v2.2.0
`spotbugs`	v2.7.1

Set SAST CI/CD variables to use local SAST analyzers

Add the following configuration to your .gitlab-ci.yml file. You must replace SECURE_ANALYZERS_PREFIX to refer to your local Docker container registry:

include:
  - template: Security/SAST.gitlab-ci.yml

variables:
  SECURE_ANALYZERS_PREFIX: "localhost:5000/analyzers"

The SAST job should now use local copies of the SAST analyzers to scan your code and generate security reports without requiring internet access.

Configure certificate checking of packages

If a SAST job invokes a package manager, you must configure its certificate verification. In an offline environment, certificate verification with an external source is not possible. Either use a self-signed certificate or disable certificate verification. Refer to the package manager's documentation for instructions.

Running SAST in SELinux

By default SAST analyzers are supported in GitLab instances hosted on SELinux. Adding a before_script in an overridden SAST job may not work as runners hosted on SELinux have restricted permissions.

Troubleshooting

SAST debug logging

Increase the Secure scanner log verbosity to debug in a global CI variable to help troubleshoot SAST jobs.

variables:
  SECURE_LOG_LEVEL: "debug"

`Error response from daemon: error processing tar file: docker-tar: relocation error`

This error occurs when the Docker version that runs the SAST job is 19.03.0. Consider updating to Docker 19.03.1 or greater. Older versions are not affected. Read more in this issue.

Getting warning message `gl-sast-report.json: no matching files`

For information on this, see the general Application Security troubleshooting section.

Error: `sast is used for configuration only, and its script should not be executed`

For information on this, see the GitLab Secure troubleshooting section.

Limitation when using rules:exists

The SAST CI template uses the rules:exists parameter. For performance reasons, a maximum number of matches are made against the given glob pattern. If the number of matches exceeds the maximum, the rules:exists parameter returns true. Depending on the number of files in your repository, a SAST job might be triggered even if the scanner doesn't support your project. For more details about this issue, see the rules:exists documentation.

SpotBugs UTF-8 unmappable character errors

These errors occur when UTF-8 encoding isn't enabled on a SpotBugs build and there are UTF-8 characters in the source code. To fix this error, enable UTF-8 for your project's build tool.

For Gradle builds, add the following to your build.gradle file:

compileJava.options.encoding = 'UTF-8'
tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

For Maven builds, add the following to your pom.xml file:

<properties>
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

Flawfinder encoding error

This occurs when Flawfinder encounters an invalid UTF-8 character. To fix this, convert all source code in your project to UTF-8 character encoding. This can be done with cvt2utf or iconv either over the entire project or per job using the before_script feature.

Semgrep slowness, unexpected results, or other errors

If Semgrep is slow, reports too many false positives or false negatives, crashes, fails, or is otherwise broken, see the Semgrep docs for troubleshooting GitLab SAST.

SAST job fails with message `strconv.ParseUint: parsing "0.0": invalid syntax`

Invoking Docker-in-Docker is the likely cause of this error. Docker-in-Docker is:

Disabled by default in GitLab 13.0 and later.
Unsupported from GitLab 13.4 and later.

Several workarounds are available. From GitLab version 13.0 and later, you must not use Docker-in-Docker.

Workaround 1: Pin analyzer versions (GitLab 12.1 and earlier)

Set the following variables for the SAST job. This pins the analyzer versions to the last known working version, allowing SAST with Docker-in-Docker to complete as it did previously:

sast:
  variables:
    SAST_DEFAULT_ANALYZERS: ""
    SAST_ANALYZER_IMAGES: "registry.gitlab.com/gitlab-org/security-products/analyzers/bandit:2.9.6, registry.gitlab.com/gitlab-org/security-products/analyzers/brakeman:2.11.0, registry.gitlab.com/gitlab-org/security-products/analyzers/eslint:2.10.0, registry.gitlab.com/gitlab-org/security-products/analyzers/flawfinder:2.11.1, registry.gitlab.com/gitlab-org/security-products/analyzers/gosec:2.14.0, registry.gitlab.com/gitlab-org/security-products/analyzers/nodejs-scan:2.11.0, registry.gitlab.com/gitlab-org/security-products/analyzers/phpcs-security-audit:2.9.1, registry.gitlab.com/gitlab-org/security-products/analyzers/pmd-apex:2.9.0, registry.gitlab.com/gitlab-org/security-products/analyzers/secrets:3.12.0, registry.gitlab.com/gitlab-org/security-products/analyzers/security-code-scan:2.13.0, registry.gitlab.com/gitlab-org/security-products/analyzers/sobelow:2.8.0, registry.gitlab.com/gitlab-org/security-products/analyzers/spotbugs:2.13.6, registry.gitlab.com/gitlab-org/security-products/analyzers/tslint:2.4.0"

Remove any analyzers you don't need from the SAST_ANALYZER_IMAGES list. Keep SAST_DEFAULT_ANALYZERS set to an empty string "".

Workaround 2: Disable Docker-in-Docker for SAST and Dependency Scanning (GitLab 12.3 and later)

Disable Docker-in-Docker for SAST. Individual <analyzer-name>-sast jobs are created for each analyzer that runs in your CI/CD pipeline.

include:
  - template: SAST.gitlab-ci.yml

variables:
  SAST_DISABLE_DIND: "true"

Workaround 3: Upgrade to GitLab 13.x and use the defaults

From GitLab 13.0, SAST defaults to not using Docker-in-Docker. In GitLab 13.4 and later, SAST using Docker-in-Docker is no longer supported. If you have this problem on GitLab 13.x and later, you have customized your SAST job to use Docker-in-Docker. To resolve this, comment out any customizations you've made to your SAST CI job definition and follow the documentation to reconfigure, using the new and improved job definition default values.

include:
  - template: Security/SAST.gitlab-ci.yml
