CVE-2025-59017Network attack vector

Authenticated data compromise via unguarded AJAX routes

Published Sep 9, 2025 · Updated Sep 9, 2025

Broken access control in affected TYPO3 CMS releases allows remote authenticated users to read, modify, or delete data through backend AJAX routes. Dedicated module routes accept direct requests without inheriting the permission checks enforced by their corresponding backend modules. A valid backend account is required, but access to the targeted module is not, so low-privileged users can bypass module restrictions.
