Summary

MariaDB server from 10.6.1 before 10.6.28, 10.11.1 before 10.11.19, 11.4.1 before 11.4.13, 11.8.1 before 11.8.9, 12.3.1 before 12.3.3 and 13.0.1 before 13.0.2 is affected. The mariadb.service unit uses the file /run/mysqld/wsrep-new-cluster during the next service restart, a flaw tied to CWE-15. A database user with the FILE privilege, where secure-file-priv permits writes to /run/mysqld, can create that file and inject environment values into the restarted service.

Description from the CNA

MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, the mariadb.service unit used /run/mysqld/wsrep-new-cluster during the next service restart. A database user with FILE privilege and a secure-file-priv configuration permitting writes to /run/mysqld could create that file and inject attacker-controlled environment values into the restarted service. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.
