Auth bypass in TYPO3 Extension "TYPO3 Ai Integration Extension"

CVE-2026-112239

The extension provides a backend endpoint that writes a submitted value into a submitted field of a submitted page record. It neither checks the user's permissions nor limits which fields can be changed. Any authenticated backend user can therefore change any property of any page, including its access permissions and configuration, outside the scope granted to them.

Vulnerability class: Broken Access Control
