Problem When performing a database query involving multiple tables through the database abstraction layer (DBAL), frontend user permissions are only applied via `FrontendGroupRestriction` to the last table. As a result, data from additional tables included in the same query may be unintentionally exposed to unauthorized users. Solution Update to TYPO3 versions 9.5.51 ELTS, 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, 13.4.12 LTS that fix the problem described. Credits Thanks to Christian Futterlieb for reporting this issue, and to TYPO3 security team member Elias Häußler for fixing it.
