What it is

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 allow a remote attacker with query-execution access to invoke an XQuery evaluation function without the additional required evaluation privilege, which could result in server-side code execution with elevated permissions.
