CVE-2023-52969Network attack vector

Authenticated server crash via crafted INSERT SELECT

Published Mar 8, 2025 · Updated Nov 3, 2025

Denial of service in MariaDB Server affected branches allows remote authenticated users to crash the server via crafted INSERT SELECT queries. During optimization, derived-table handling retains the statement's target table in the SELECT path and reaches invalid state in make_aggr_tables_info or optimize_stage2. A highly privileged database account able to create tables and execute data-modifying queries can terminate the server, interrupting database availability.
