Problem Description
In addition to the vulnerability documented in TYPO3‑CORE‑SA‑2025‑021 (CVE‑2025‑59017), any authenticated backend user could invoke a backend AJAX route belonging to the workspaces module.
The route allowed the caller to request arbitrary data from the database, without performing a permission check on the target table. Consequently, a backend user without rights to a particular database table could retrieve sensitive records, leading to information disclosure.
Solution
Update to TYPO3 versions 9.5.55 ELTS, 10.4.54 ELTS, 11.5.48 ELTS, 12.4.37 LTS, 13.4.18 LTS that fix the problem described.
