Go to dashboardMariaDB server versions 12.3.1 through 12.3.3 and 13.0.2 mishandle SYS_REFCURSOR cursor-array reallocation, leaving stale references that cause a use-after-free. A low-privileged database user can trigger it, and it can enable remote code execution when chained with another vulnerability.

Run SELECT VERSION(); on the MariaDB server and check whether it reports 12.3.1, 12.3.2, or 13.0.0-13.0.2 range builds before the fixed releases.
Upgrade MariaDB to 12.3.3 or 13.0.2 (or later in the same branch).

MariaDB server is a community developed fork of MySQL server. From 12.3.1 until 12.3.3 and 13.0.2, SYS_REFCURSOR handling is affected because cursor-array reallocation can leave stale references in routine contexts. A low-privileged attacker can open a large number of SYS_REFCURSORs and then fetch one to trigger a use-after-free that can enable remote code execution when combined with another vulnerability. This issue is fixed in versions 12.3.3 and 13.0.2.
