What is CVE-2025-47941?

A serious vulnerability exists in the TYPO3 Content Management System where the multifactor authentication (MFA) process can be bypassed during backend login. This issue arises from inadequate enforcement of access restrictions across all backend routes, allowing unauthorized users to gain access post-authentication. The vulnerability is only exploitable with valid backend user credentials, and users are strongly advised to update to TYPO3 version 12.4.31 LTS or 13.4.12 LTS to mitigate this risk.
