A flaw was found in MariaDB server. This vulnerability allows a low-privileged authenticated user to bypass a security control that normally restricts file operations. Specifically, the system failed to verify the necessary 'FILE' privilege when certain 'SELECT' statements, which write data to files, were executed with subqueries in their 'FROM' clause. This could enable an attacker to write unauthorized files to the server's file system, potentially leading to the disclosure of sensitive information or a denial of service by corrupting or filling disk space.
