TYPO3 CMS Allows Broken Access Control in Redirects Module
Date: 2026-01
Affected: composer/typo3/cms-redirects, composer/typo3/cms-redirects, composer/typo3/cms-redirects
Attack vector: phishing
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2025-59021
CWE: CWE-862

### Problem 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. ### Credits Thanks to Georg Dümmler for reporting this issue, and to TYPO3 security team member Elias Häußler for fixing it. ### References * [TYPO3-CORE-SA-2026-002](https://typo3.org/security/advisory/typo3-core-sa-2026-002)
