TYPO3-CORE-SA-2024-007: HTML Injection in History Module

Categories: Development, TYPO3 CMS Created by Oliver Hader
It has been discovered that TYPO3 CMS is vulnerable to HTML injection.

Problem Description

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.


Update to TYPO3 version 13.1.1 that fixes the problem described.


Thanks to TYPO3 core team member Andreas Kienast who reported this issue and to TYPO3 core & security team Benjamin Franzke who fixed the issue.
