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
Authenticated backend users were able to retrieve file metadata via several Backend API routes without proper permission checks, allowing access to files outside their permitted file mounts or storages. This issue affects TYPO3 CMS versions before 10.4.57, 11.0.0-11.5.50, 12.0.0-12.4.45, 13.0.0-13.4.30 and 14.0.0-14.3.2.

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-862

The application checks who you are but not whether you're allowed to perform a given action, so any authenticated user can reach things meant for others. This is the classic “change the ID in the URL” bug. The fix is an authorization check on every request, evaluated against the acting user's permissions.

Recommended fix High confidence

Upgrade to TYPO3 CMS 10.4.57, 11.5.50, 12.4.45, 13.4.30, or 14.3.2 (select the appropriate version for your current branch)

  1. Review the TYPO3 change log for your current version to understand changes and potential breaking changes
  2. Back up your database and file system before upgrading
  3. Test the upgrade in a staging environment before applying to production
  4. Upgrade to one of the fixed versions: 10.4.57, 11.5.50, 12.4.45, 13.4.30, or 14.3.2 (depending on your branch)
  5. After upgrade, verify file mount and storage permissions are functioning correctly for backend users
  6. Clear all caches after upgrading (via Install Tool or CLI)
Caveat Review TYPO3 change logs for your version branch as minor version upgrades may include breaking changes to extensions or configuration
