Description
MariaDB server versions from 10.6.1 up to but not including 10.6.28, and specific later versions including 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, contain a vulnerability involving the #mysql50# prefix. This prefix bypasses normal table-name filesystem encoding, allowing attackers to access files using legacy unencoded names. Exploitation can lead to crashes, data corruption, data exfiltration, or remote code execution. The issue is fixed in the specified versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.
