TYPO3 Allows Information Disclosure via DBAL Restriction Handling
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.
