Administrative database compromise via unrestricted SQL queries

Published May 26, 2026 · Updated May 26, 2026

SQL injection in OpenKM 6.3.12 allows remote authenticated users to read, modify, or delete application database records. The DatabaseQuery interface passes the attacker-controlled qs parameter from /admin/DatabaseQuery to the application database as an unrestricted SQL statement. Administrative privileges are required; Community Edition through 6.3.12 and Professional Edition through 7.1.47 are affected, enabling password-hash disclosure, permission changes, or record deletion.
