Problem Password hashes were being reflected in the editing forms of the TYPO3 backend user interface. This allowed attackers to crack the plaintext password using brute force techniques. Exploiting this vulnerability requires a valid backend user account. Solution Update to TYPO3 versions 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, 13.0.1 that fix the problem described.
