Problem

Restricting frontend login to specific users, organized in different storage folders (partitions), can be bypassed. A potential attacker might use this ambiguity in usernames to get access to a different account - however, credentials must be known to the adversary.

Solution

Update to TYPO3 versions 8.7.49 ELTS, 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1 that fix the problem described above.
