As written in the advisory (Markdown source, shown as plain text).

### Problem The history backend module is vulnerable to HTML injection. Although Content-Security-Policy headers effectively prevent JavaScript execution, adversaries can still inject malicious HTML markup. Exploiting this vulnerability requires a valid backend user account. ### Solution Update to TYPO3 version 13.1.1 that fixes the problem described. ### Credits Thanks to TYPO3 core team member Andreas Kienast who reported this issue and to TYPO3 core & security team Benjamin Franzke who fixed the issue. ### References * [TYPO3-CORE-SA-2024-007](https://typo3.org/security/advisory/typo3-core-sa-2024-007)
