Problem Description
Backend users with access to the redirects module and write permission on the sys_redirect table were able to read, create, and modify any redirect record - without restriction to the user’s own file‑mounts or web‑mounts. This allowed attackers to insert or alter redirects pointing to arbitrary URLs - facilitating phishing or other malicious redirect attacks.
Solution
Update to TYPO3 versions 10.4.55 ELTS, 11.5.49 ELTS, 12.4.41 LTS, 13.4.23 LTS, 14.0.2 that fix the problem described.
