TYPO3 CMS: Broken Access Control in Media Module

  • Disclosed: 12.06.2026
  • Updated: 11.10.2026 10:22

Problem

Backend users were able to insert arbitrary records and files into the TYPO3 clipboard without proper read permission checks, which allowed users to gather information about records and files they were not authorized to view.

Solution

Update to TYPO3 versions 10.4.57 ELTS, 11.5.51 ELTS, 12.4.46 ELTS, 13.4.31 LTS, 14.3.3 LTS that fix the problem described.
