Denial of Service in TYPO3 Bookmark Toolbar

  • Disclosed: 08.10.2024
  • Updated: 11.10.2026 10:22

Problem

Due to insufficient input validation, manipulated data saved in the bookmark toolbar of the backend user interface causes a general error state, blocking further access to the interface. Exploiting this vulnerability requires an administrator-level backend user account.

Solution

Update to TYPO3 versions 10.4.46 ELTS, 11.5.40 LTS, 12.4.21 LTS, 13.3.1 that fix the problem described.

Credits

Thanks to Hendrik Eichner who reported this issue and to TYPO3 core & security team members Oliver Hader and Benjamin Franzke who fixed the issue.
