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
A cross-site scripting issue has been discovered in GitLab CE/EE affecting all versions from 13.5 prior to 15.3.5, 15.4 prior to 15.4.4, and 15.5 prior to 15.5.2. It was possible to exploit a vulnerability in setting the Jira Connect integration which could lead to a reflected XSS that allowed 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
How this class of weakness works · CWE-79

Untrusted input is placed into a web page without being neutralised, so an attacker's markup or script executes in another user's browser. That can hijack sessions, capture keystrokes, or silently perform actions as the victim. Fixing it properly means context-aware output encoding everywhere data meets HTML, backed by a content-security policy as a second line of defence.

Recommended fix High confidence

GitLab 15.4.6, 15.5.5, or 15.6.1 (or later) depending on your current branch

  1. 1. Identify the current GitLab installation version using `sudo gitlab-rake gitlab:env:info` or checking the GitLab admin area.
  2. 2. Based on the current version, plan the upgrade path to a fixed release.
  3. 3. For GitLab 13.5.x through 15.2.x: upgrade to GitLab 15.3.5 or later.
  4. 4. For GitLab 15.4.x: upgrade to GitLab 15.4.6 or later.
  5. 5. For GitLab 15.5.x: upgrade to GitLab 15.5.5 or later.
  6. 6. For GitLab 15.6.0: upgrade to GitLab 15.6.1 or later.
  7. 7. Review GitLab upgrade documentation for your deployment method (Omnibus, source, or Docker) before proceeding.
  8. 8. Perform a full backup of the GitLab instance before upgrading.
Caveat Standard GitLab upgrade risks apply - review release notes for deprecations and ensure compatibility with your plugins and integrations before upgrading
