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.

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

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 (ULTIMATE)
- Introduced in GitLab Ultimate 13.3.
- Improved in GitLab Ultimate 13.4.
- Improved in GitLab Ultimate 13.5.
You can enable and configure SAST with a basic configuration using the SAST Configuration page:
-
From the project's home page, go to Security & Compliance > Configuration in the left sidebar.
-
If the project does not have a
.gitlab-ci.yml
file, click Enable in the Static Application Security Testing (SAST) row, otherwise click 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.
-
Click 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 are pinning to a specific patch version of the spotbugs
analyzer:
include:
- template: Security/SAST.gitlab-ci.yml
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
andgosec
).
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
andsobelow
by matching the corresponding identifiers'type
andvalue
:[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 filegosec-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.
FLAG:
On self-managed GitLab, by default this feature is not available. To make it available, ask an administrator to enable the vulnerability_flags
flag. On GitLab.com, this feature is available.
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.
Read more on how to use private Maven repositories.
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. |

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
orkubernetes
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 |

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

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.
