CVSS 9 CRITICAL
A flaw was found in MariaDB. During a State Snapshot Transfer (SST), the donor node improperly validates parameters sent by a joiner node. This vulnerability allows a malicious joiner to execute arbitrary shell commands on the donor server through the mariabackup SST method. This could lead to a complete compromise of the donor system.
