TYPO3 before 13.3.1 allows denial of service (interface error) in the Bookmark Toolbar (ext:backend), exploitable by an administrator-level backend user account via manipulated data saved in the bookmark toolbar of the backend user interface. The fixed versions are 10.4.46 ELTS, 11.5.40 LTS, 12.4.21 LTS, and 13.3.1.

### 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. ### References * [TYPO3-CORE-SA-2024-011](https://typo3.org/security/advisory/typo3-core-sa-2024-001)
