GitLab CI/CD job token

DETAILS: Tier: Free, Premium, Ultimate Offering: SaaS, self-managed

When a CI/CD pipeline job is about to run, GitLab generates a unique token and makes it available to the job as the CI_JOB_TOKEN predefined variable. The token is valid only while the job is running. After the job finishes, the token access is revoked and you cannot use the token anymore.

Use a CI/CD job token to authenticate with certain GitLab features from running jobs. The token receives the same access level as the user that triggered the pipeline, but has access to fewer resources than a personal access token. A user can cause a job to run with an action like pushing a commit, triggering a manual job, or being the owner of a scheduled pipeline. This user must be have a role that has the required privileges to access the resources.

You can use a job token to authenticate with GitLab to access another project's resources (the target project). By default, the job token's project must be added to the target project's allowlist.

If a project is public or internal, you can access some features without being on the allowlist. For example, you can fetch artifacts from the project's public pipelines. This access can also be restricted.

A job token can access a project's resources without any configuration, but it might give extra permissions that aren't necessary. There is a proposal to redesign the feature for more granular control of access permissions.

GitLab CI/CD job token security

If a job token is leaked, it could potentially be used to access private data accessible to the user that triggered the CI/CD job. To help prevent leaking or misuse of this token, GitLab:

• Masks the job token in job logs.
• Grants permissions to the job token only when the job is running.

You should also configure your runners to be secure:

• Avoid using Docker privileged mode if the machines are re-used.
• Avoid using the shell executor when jobs run on the same machine.

An insecure GitLab Runner configuration increases the risk that someone can steal tokens from other jobs.

Control job token access to your project

You can control which projects can use a job token to authenticate and access your project's resources.

By default, job token access is restricted to only CI/CD jobs that run in pipelines in your project. To allow another project to authenticate with a job token from the other project's pipeline:

• You must add the project to the job token allowlist.
• The user that triggers the job must be a member of your project.
• The user must have the permissions to perform the action.

If your project is public or internal, some publicly accessible resources can be accessed with a job token from any project. These resources can also be limited to only projects on the allowlist.

Add a project to the job token allowlist

• Introduced in GitLab 15.9. Deployed behind the :inbound_ci_scoped_job_token feature flag, enabled by default.
• Feature flag removed in GitLab 15.10.
• Allow access to this project with a CI_JOB_TOKEN setting renamed to Limit access to this project in GitLab 16.3.

You can add projects to your job token allowlist to allow access your project's resources with a job token for authentication. By default, the allowlist of any project only includes itself.

For example, project A can add project B to project A's allowlist. CI/CD jobs in project B (the "allowed project") can now use CI/CD job tokens to authenticate API calls to access project A.

Add projects to the allowlist only when cross-project access is needed.

Prerequisites:

• You must have at least the Maintainer role in the current project. If the allowed project is internal or private, you must have at least the Guest role in that project.
• You must not have more than 200 projects added to the allowlist.

To add a project to the allowlist:

1. On the left sidebar, select Search or go to and find your project.
2. Select Settings > CI/CD.
3. Expand Token Access.
4. Ensure the Limit access to this project toggle is enabled. Enabled by default in new projects. It is a security risk to disable this feature, so project maintainers or owners should keep this setting enabled at all times.
5. Select Add project.
6. Input the path to the project to add to the allowlist, and select Add project.

You can also add a project to the allowlist with the API.

Limit job token scope for public or internal projects

• Introduced in GitLab 16.6.

Projects not in the allowlist can use a job token to authenticate with public or internal projects to:

• Fetch artifacts.
• Access the container registry.
• Access the package registry.
• Access releases, deployments, and environments.

You can limit access to these actions to only the projects on the allowlist by setting each feature to be only visible to project members.

Prerequisites:

• You must have the Maintainer role for the project.

To set a feature to be only visible to project members:

1. On the left sidebar, select Search or go to and find your project.
2. Select Settings > General.
3. Expand Visibility, project features, permissions.
4. Set the visibility to Only project members for the features you want to restrict access to.
   • The ability to fetch artifacts is controlled by the CI/CD visibility setting.
5. Select Save changes.

Allow any project to access your project

• Allow access to this project with a CI_JOB_TOKEN setting renamed to Limit access to this project in GitLab 16.3.

WARNING: It is a security risk to disable the token access limit and allowlist. A malicious user could try to compromise a pipeline created in an unauthorized project. If the pipeline was created by one of your maintainers, the job token could be used in an attempt to access your project.

If you disable the Limit access to this project setting, the allowlist is ignored. Jobs from any project could access your project with a job token if the user that triggers the pipeline has permission to access your project.

You should only disable this setting for testing or a similar reason, and you should enable it again as soon as possible.

Prerequisites:

• You must have at least the Maintainer role for the project.

To disable the job token scope allowlist:

1. On the left sidebar, select Search or go to and find your project.
2. Select Settings > CI/CD.
3. Expand Token Access.
4. Toggle Limit access to this project to disabled. Enabled by default in new projects.

You can also enable and disable the setting with the API.

Use a job token to clone a private project's repository

You can use the job token to authenticate and clone a repository from a private project in a CI/CD job. For example:

git clone https://gitlab-ci-token:${CI_JOB_TOKEN}@gitlab.example.com/<namespace>/<project>

You can use this job token to clone a repository even if the HTTPS protocol is disabled by group, project, or instance settings. You cannot use a job token to push to a repository, but issue 389060 proposes to change this behavior.

Limit your project's job token access (deprecated)

• Introduced in GitLab 14.1. Deployed behind the :ci_scoped_job_token feature flag, disabled by default.
• Enabled on GitLab.com and self-managed in GitLab 14.4.
• Feature flag removed in GitLab 14.6.

NOTE: The Limit access from this project setting is disabled by default for all new projects and is scheduled for removal in GitLab 17.0. Project maintainers or owners should configure the Limit access to this project setting instead.

Control your project's job token scope by creating an allowlist of projects which can be accessed by your project's job token.

By default, the allowlist includes your current project. Other projects can be added and removed by maintainers with access to both projects.

With the setting disabled, all projects are considered in the allowlist and the job token is limited only by the user's access permissions.

For example, when the setting is enabled, jobs in a pipeline in project A have a CI_JOB_TOKEN scope limited to project A. If the job needs to use the token to make an API request to project B, then B must be added to the allowlist for A.

Configure the job token scope (deprecated)

• Limit CI_JOB_TOKEN access setting renamed to Limit access from this project in GitLab 16.3.

Prerequisites:

• You must not have more than 200 projects added to the token's scope.

To configure the job token scope:

1. On the left sidebar, select Search or go to and find your project.
2. Select Settings > CI/CD.
3. Expand Token Access.
4. Toggle Limit access from this project to enabled.
5. Optional. Add existing projects to the token's access scope. The user adding a project must have the Maintainer role in both projects.

Troubleshooting

CI job token failures are usually shown as responses like 404 Not Found or similar:

• Unauthorized Git clone:

  $ git clone https://gitlab-ci-token:$CI_JOB_TOKEN@gitlab.com/fabiopitino/test2.git
  
  Cloning into 'test2'...
  remote: The project you were looking for could not be found or you don't have permission to view it.
  fatal: repository 'https://gitlab-ci-token:[MASKED]@gitlab.com/<namespace>/<project>.git/' not found

While troubleshooting CI/CD job token authentication issues, be aware that:

• A GraphQL example mutation is available to toggle the scope settings per project.
• This comment demonstrates how to use GraphQL with Bash and cURL to:
  • Enable the inbound token access scope.
  • Give access to project B from project A, or add B to A's allowlist.
  • To remove project access.
• The CI job token becomes invalid if the job is no longer running, has been erased, or if the project is in the process of being deleted.
