CVSS 9 CRITICAL
A flaw was found in MariaDB server. When the `wsrep_notify_cmd` feature is enabled, a remote attacker could exploit this vulnerability by embedding shell commands in the name of a joiner node. This could lead to arbitrary code execution on the server, allowing the attacker to take full control of the affected system.
