CVSS Score
-The vulnerability stems from missing session termination after password changes. In TYPO3 frontend user management, the controller action responsible for password updates (typically updateAction) would be the logical location where session revocation should occur. The extension's failure to call session invalidation methods (like FrontendUserAuthentication::logoff() or session removal) in this workflow directly matches the described vulnerability. While no direct code diffs are available, the vulnerability pattern and TYPO3's architecture strongly indicate the password update handler as the vulnerable component.
