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
An issue in Incident Timelines has been discovered in GitLab CE/EE affecting all versions starting from 14.9 before 15.1.6, all versions starting from 15.2 before 15.2.4, all versions starting from 15.3 before 15.3.2.which allowed an authenticated attacker to inject arbitrary content. A victim interacting with this content could lead to arbitrary requests.

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 confidence

A stored cross-site scripting (XSS) vulnerability in GitLab's Incident Timelines feature allows authenticated attackers to inject arbitrary JavaScript content. When victims view the timeline, the injected code executes, enabling the attacker to perform arbitrary requests on behalf of the authenticated victim (likely via session hijacking or CSRF).

MitigationUpgrade GitLab to version 15.1.6, 15.2.4, 15.3.2 or later. If immediate upgrade is not feasible, consider restricting access to the Incident Timelines feature or implementing Content Security Policy headers as a temporary mitigation.

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 installed GitLab version
    Access the GitLab help page (click the Help icon or navigate to /help in your GitLab instance) or query the API endpoint GET /api/v4/version to retrieve the running version number
    Affected if The version returned is 14.9.0 through 15.1.5, 15.2.0 through 15.2.3, or 15.3.0 through 15.3.1 (these fall within the vulnerable ranges)
  2. Confirm Incident Timelines feature is accessible
    Navigate to a project in GitLab, go to the Incidents section (available under Project > Incidents), and verify that the Timelines tab exists and is accessible to authenticated users
    Affected if The Timelines feature is present and viewable by users in the affected version range
  3. Check if user has permissions to create incidents
    As an authenticated user with Developer or higher role in a project, attempt to create a new incident and access the Timelines functionality within that incident
    Affected if Users can create incidents and access timeline entries in the affected version range, providing an attack surface for XSS injection

Your environment is affected if you are running a GitLab version within 14.9.0 to 15.1.5, 15.2.0 to 15.2.3, or 15.3.0 to 15.3.1 AND the Incident Timelines feature is accessible to authenticated users in your instance.

Upgrade available Upgrade to 15.1.6 / 15.2.4 / 15.3.2 or later
Fixed in 15.1.615.2.415.3.2
Interim mitigation

Upgrade GitLab to version 15.1.6, 15.2.4, 15.3.2 or later. If immediate upgrade is not feasible, consider restricting access to the Incident Timelines feature or implementing Content Security Policy headers as a temporary mitigation.

Recommended fix High confidence

15.1.6 (for 14.9-15.1), 15.2.4 (for 15.2), or 15.3.2 (for 15.3), or latest stable release

  1. Check current GitLab version using `sudo gitlab-rake gitlab:version` or `/help/version` in the web UI
  2. Identify the appropriate upgrade path based on your current version: 14.9.x-15.1.x upgrade to 15.1.6+, 15.2.x upgrade to 15.2.4+, or 15.3.x upgrade to 15.3.2+
  3. Back up your GitLab instance including database and repositories before upgrading
  4. Update your GitLab package repository: `sudo apt-get update` for Debian/Ubuntu or `sudo yum check-update` for RHEL/CentOS
  5. Install the updated GitLab package matching your distribution (e.g., `sudo apt-get install gitlab-ee` or `sudo yum install gitlab-ee`)
  6. Reconfigure GitLab: `sudo gitlab-ctl reconfigure`
  7. Restart GitLab services if required: `sudo gitlab-ctl restart`
  8. Verify the upgrade was successful by checking the version again
