CVE-2025-1250
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 · uneditedAn issue has been discovered in GitLab CE/EE affecting all versions from 15.0 before 18.1.6, 18.2 before 18.2.6, and 18.3 before 18.3.2 that could have allowed an authenticated user to stall background job processing by sending specially crafted commit messages, merge request descriptions, or notes.
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 · high confidenceAn authenticated user can cause denial of service by submitting specially crafted commit messages, merge request descriptions, or notes that stall GitLab background job processing, affecting availability of automated workflows.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm GitLab is installedCheck for GitLab installation by looking for gitlab-rails command or checking /opt/gitlab directory: ls -la /opt/gitlab 2>/dev/null || which gitlab-railsAffected if GitLab is not installed on this system
-
Determine installed GitLab versionRun gitlab-rake gitlab:version or check /opt/gitlab/version-manifest.txt to obtain the exact version numberAffected if Version cannot be determined or is outside the affected range
-
Compare version against affected rangesCompare your installed version to: >= 15.0.0 AND < 18.1.6, OR >= 18.2.0 AND < 18.2.6, OR >= 18.3.0 AND < 18.3.2Affected if Your version falls within any of these ranges
-
Verify GitLab service is runningCheck if GitLab is operational: gitlab-ctl status or systemctl status gitlab-runsvdirAffected if GitLab is actively running and processing requests
-
Confirm authenticated user access is possibleReview whether user authentication is enabled in GitLab settings. Check in Admin Area > Settings > General > Sign-up restrictionsAffected if Authentication is enabled allowing user accounts to submit commit messages, merge requests, or notes
You are affected if GitLab is installed, running a version within 15.0.0 to 18.1.5, 18.2.0 to 18.2.5, or 18.3.0 to 18.3.1, and authenticated users can submit content to the system.

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.
dbcve · scoped18.1.618.2.618.3.2
Upgrade GitLab to version 18.1.6, 18.2.6, 18.3.2 or later to patch the vulnerability.
18.3.2 (or latest stable 18.x release)
- Backup the GitLab database and configuration before proceeding with any upgrade
- Update GitLab to the latest patched version (18.3.2 or later for the 18.3 branch, 18.2.6 for the 18.2 branch, or 18.1.6 for the 18.1 branch)
- Run 'sudo gitlab-ctl reconfigure' after the upgrade completes
- Verify background job processing is functioning normally by checking the GitLab admin area
