Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
GitLab has remediated an issue in EE affecting all versions from 17.1 before 18.3.5, 18.4 before 18.4.3, and 18.5 before 18.5.1 that could have allowed an authenticated attacker with specific permissions to hijack project runners from other projects.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

GitLab EE versions 17.1 through 18.5 before specific patch releases contained an authorization flaw that allowed an authenticated attacker with certain project permissions to hijack CI/CD runners belonging to other projects, enabling unauthorized execution of pipelines under compromised runner contexts.

MitigationUpgrade GitLab EE to versions 18.3.5, 18.4.3, 18.5.1 or later to remediate the runner hijacking vulnerability. Review runner configurations and audit runner assignment permissions post-upgrade.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify GitLab EE version
    Run `sudo gitlab-rake gitlab:version` or check the GitLab admin area under Help > Version to see the exact installed version
    Affected if The installed version falls within >= 17.1.0 and < 18.3.5, OR >= 18.4.0 and < 18.4.3, OR equals 18.5.0
  2. Verify CI/CD runners exist
    Navigate to Settings > CI/CD > Runners in the GitLab UI or query the API endpoint `/api/v4/runners` with admin credentials to list registered runners
    Affected if Runners are registered and active in the GitLab instance
  3. Check runner assignment permissions
    Review project-level runner settings under Settings > CI/CD > Runners for each project; verify if projects share runners or have runner permissions that allow cross-project assignment
    Affected if Runners are shared across multiple projects or non-owner users can modify runner assignments

You are affected if your GitLab EE version is one of the vulnerable releases AND you have CI/CD runners configured that could be reassigned by users with project access rights.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade available Upgrade to 18.3.5 / 18.4.3 or later
Fixed in 18.3.518.4.3
Interim mitigation

Upgrade GitLab EE to versions 18.3.5, 18.4.3, 18.5.1 or later to remediate the runner hijacking vulnerability. Review runner configurations and audit runner assignment permissions post-upgrade.

Recommended fix High confidence

GitLab 18.5.1 (or latest 18.x stable)

  1. 1. Backup your GitLab instance data and configuration
  2. 2. Schedule a maintenance window as upgrade may require downtime
  3. 3. For GitLab 17.1.x through 18.3.4: Upgrade to GitLab 18.3.5 or later
  4. 4. For GitLab 18.4.0 through 18.4.2: Upgrade to GitLab 18.4.3 or later
  5. 5. For GitLab 18.5.0: Upgrade to GitLab 18.5.1 or later
  6. 6. After upgrade, verify runner configuration in Admin Area > Runners to confirm no unauthorized changes
  7. 7. Review project runner assignments in affected projects to ensure integrity
Caveat Major version upgrades (e.g., 17.x to 18.x) may require database migrations and have longer downtime; review GitLab upgrade documentation for prerequisites
