CVE-2023-2015
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 starting from 15.8 before 15.10.8, all versions starting from 15.11 before 15.11.7, all versions starting from 16.0 before 16.0.2. A reflected XSS was possible when creating new abuse reports which allows attackers to perform arbitrary actions on behalf of victims.
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 confidenceA reflected cross-site scripting (XSS) vulnerability exists in GitLab CE/EE abuse report creation functionality across versions 15.8 through 16.0.2. Attackers can craft malicious URLs containing JavaScript payloads that execute in victims' browsers when they create new abuse reports, enabling session hijacking and actions performed on behalf of authenticated users.

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.
-
Identify GitLab versionLog into the GitLab administrative interface and navigate to the Admin Area, or access the /about page, to view the installed GitLab version numberAffected if The displayed version falls within 15.8.0 to 15.10.7, 15.11.0 to 15.11.6, or 16.0.0 to 16.0.2 (the vulnerable ranges)
-
Confirm version via command lineRun `gitlab-rake gitlab:env:info` on the GitLab server to retrieve the exact installed versionAffected if The version output matches the vulnerable ranges listed above
-
Verify abuse report feature is accessibleNavigate to a project or user profile and locate the abuse report or report abuse option (typically found under user profiles or project settings)Affected if The feature is available and reachable in the installation
If the installed GitLab version is 15.8.0 through 16.0.2 (excluding the patched points 15.10.8, 15.11.7, and 16.0.2) and the abuse report functionality is accessible, the environment is vulnerable to CVE-2023-2015.

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 · scoped15.10.815.11.716.0.2
Upgrade GitLab to version 15.10.8, 15.11.7, or 16.0.2 or later. Until patched, users should not click untrusted links leading to abuse report creation pages.
16.0.2 (or latest 16.0.x stable release)
- 1. Back up your GitLab instance database and configuration
- 2. Ensure you are running a currently supported GitLab version
- 3. Plan maintenance window as upgrade will require brief downtime
- 4. For GitLab installations using omnibus package: run 'sudo gitlab-ctl stop' to stop services
- 5. Update to the appropriate fixed version based on your current version
- 6. For GitLab 15.8.x through 15.10.x: upgrade to 15.10.8 or later
- 7. For GitLab 15.11.x: upgrade to 15.11.7 or later
- 8. For GitLab 16.0.x: upgrade to 16.0.2 or later
