CVE-2026-77127
The extension fails to restrict a backend AJAX endpoint for inline editing to fields the current user is permitted to see or edit.
Overview
CVE-2026-77127 is a known-severity vulnerability. It was published on August 25, 2026.
Technical description
The extension fails to restrict a backend AJAX endpoint for inline editing to fields the current user is permitted to see or edit. An authenticated, low-privileged backend user can supply arbitrary table, field and record parameters, and trigger an error response that discloses the current database value of the requested field, leading to disclosure of sensitive information such as backend and frontend user password hashes. Exploitation requires a valid, authenticated TYPO3 backend user account with access to the extensions backend module.
