Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 do not sufficiently isolate user-supplied code executed through certain REST and XDBC evaluation paths from HTTP request, response, and session state. An attacker able to execute code through an affected path could perform unauthorized actions or compromise an authenticated session.
