## What is CVE-2025-47941?

CVE-2025-47941 is a high-severity authentication bypass vulnerability in Typo3 Typo3, published on 20 May 2025. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

TYPO3 is an open source, PHP based web content management system. In versions on the 12.x branch prior to 12.4.31 LTS and the 13.x branch prior to 13.4.2 LTS, the multifactor authentication (MFA) dialog presented during backend login can be bypassed due to insufficient enforcement of access restrictions on all backend routes. Successful exploitation requires valid backend user credentials, as MFA can only be bypassed after successful authentication. Users should update to TYPO3 version 12.4.31 LTS or 13.4.12 LTS to fix the problem.

Weakness: CWE-288 (Authentication Bypass Using an Alternate Path or Channel)
