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 has been discovered in GitLab EE affecting all versions starting from 12.8 before 15.11.11, all versions starting from 16.0 before 16.0.7, all versions starting from 16.1 before 16.1.2. An attacker could change the name or path of a public top-level group in certain situations.

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

An authorization bypass in GitLab EE allows authenticated attackers to modify the name or path of public top-level groups in certain situations, potentially enabling group hijacking or confusion attacks.

MitigationUpgrade GitLab to versions 15.11.11, 16.0.7, 16.1.2 or later. If immediate upgrade is not possible, restrict group modification permissions pending the patch.

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 version
    Access the GitLab administration panel or run 'gitlab-rake gitlab:env:info' to retrieve the installed GitLab version
    Affected if The version is 12.8.0 or higher but below 15.11.11, OR 16.0.0 or higher but below 16.0.7, OR 16.1.0 or higher but below 16.1.2
  2. Confirm public group existence
    Navigate to the Groups section in GitLab and filter for groups with Public visibility, focusing on top-level groups that have no parent group
    Affected if There are public top-level groups present in the GitLab instance
  3. Verify group modification permissions
    Review the permission settings for authenticated users on public groups, specifically checking if any user role has the ability to modify group name or path
    Affected if Authenticated users have permissions to edit group name or path on public groups
  4. Check audit logs for group modifications
    Review GitLab audit logs for any recent changes to public group names or paths that were performed by users without explicit group owner privileges
    Affected if Unusual or unauthorized modifications to public group names or paths are observed in the audit logs

You are affected if your GitLab version is within the affected ranges AND you have public top-level groups where authenticated users can modify group settings.

Upgrade available Upgrade to 15.11.11 / 16.0.7 / 16.1.2 or later
Fixed in 15.11.1116.0.716.1.2
Interim mitigation

Upgrade GitLab to versions 15.11.11, 16.0.7, 16.1.2 or later. If immediate upgrade is not possible, restrict group modification permissions pending the patch.

Recommended fix High confidence

GitLab 15.11.11+ (for 12.8.0-15.11.x), 16.0.7+ (for 16.0.x), or 16.1.2+ (for 16.1.x)

  1. Identify the currently installed GitLab version by running `gitlab-rake gitlab:env:info` or checking /admin/about
  2. Determine which version branch your current installation falls into: 12.8.0-15.11.x, 16.0.x, or 16.1.x
  3. For versions 12.8.0 through 15.11.x: upgrade to GitLab 15.11.11 or later (recommended: latest 15.11.x)
  4. For versions 16.0.x: upgrade to GitLab 16.0.7 or later (recommended: latest 16.0.x)
  5. For versions 16.1.x: upgrade to GitLab 16.1.2 or later (recommended: latest 16.1.x)
  6. After upgrade, verify the version with `gitlab-rake gitlab:env:info` and test group rename functionality
Caveat Major version upgrades (e.g., 15.x to 16.x) may require additional migration steps and downtime - review GitLab upgrade guides for between-major-version considerations
