GitLab CI/CD job token

When a pipeline job is about to run, GitLab generates a unique token and injects it as the CI_JOB_TOKEN predefined variable.

You can use a GitLab CI/CD job token to authenticate with specific API endpoints:

The token has the same permissions to access the API as the user that triggers the pipeline. Therefore, this user must be assigned to a role that has the required privileges.

The token is valid only while the pipeline job runs. After the job finishes, you can’t use the token anymore.

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 strategic control of the access permissions.

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

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

GitLab CI/CD job token security

To make sure that this token doesn’t leak, GitLab:

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

To make sure that this token doesn’t leak, you should also configure your runners to be secure. Avoid:

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

If you have an insecure GitLab Runner configuration, you increase the risk that someone tries to steal tokens from other jobs.

Limit GitLab CI/CD job token access

Version history

This in-development feature might not be available for your use. There can be risks when enabling features still in development. Refer to this feature’s version history for more details.

You can limit the access scope of a project’s CI/CD job token to increase the job token’s security. A job token might give extra permissions that aren’t necessary to access specific private resources. Limiting the job token access scope reduces the risk of a leaked token being used to access private data that the user associated to the job can access.

Control the job token access scope with an allowlist of other projects authorized to be accessed by authenticating with the current project’s job token. By default the token scope only allows access to the same project where the token comes from. Other projects can be added and removed by maintainers with access to both projects.

This setting is enabled by default for all new projects, and disabled by default in projects created before GitLab 14.1. It is strongly recommended that project maintainers enable this setting at all times, and configure the allowlist for cross-project access if needed.

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 a private project B, then B must be added to the allowlist for A. If project B is public or internal, it doesn’t need to be added to the allowlist. The job token scope is only for controlling access to private projects.

To enable and configure the job token scope limit:

  1. On the top bar, select Menu > Projects and find your project.
  2. On the left sidebar, select Settings > CI/CD.
  3. Expand Token Access.
  4. Toggle Limit CI_JOB_TOKEN access 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.

If the job token scope limit is disabled, the token can potentially be used to authenticate API requests to all projects accessible to the user that triggered the job.

There is a proposal to improve the feature with more strategic control of the access permissions.

Enable or disable CI job token scope limit

The GitLab CI/CD job token access scope limit is under development and not ready for production use. It is deployed behind a feature flag that is disabled by default. GitLab administrators with access to the GitLab Rails console can enable it.

To enable it:

Trigger a multi-project pipeline by using a CI job token

CI_JOB_TOKEN for multi-project pipelines was moved from GitLab Premium to GitLab Free in 12.4.

You can use the CI_JOB_TOKEN to trigger multi-project pipelines from a CI/CD job. A pipeline triggered this way creates a dependent pipeline relation that is visible on the pipeline graph.

For example:

  stage: deploy
    - curl --request POST --form "token=$CI_JOB_TOKEN" --form ref=main ""
    - if: $CI_COMMIT_TAG

If you use the CI_PIPELINE_SOURCE predefined CI/CD variable in a pipeline triggered this way, the value is pipeline (not triggered).

Download an artifact from a different pipeline

CI_JOB_TOKEN for artifacts download with the API was introduced in GitLab 9.5.

You can use the CI_JOB_TOKEN to access artifacts from a job created by a previous pipeline. You must specify which job you want to retrieve the artifacts from:

  stage: test
    - apt update && apt install -y unzip
    - curl --location --output "$CI_JOB_TOKEN"
    - unzip
