What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 can evaluate user-controlled values supplied to certain higher-order XQuery functions in an elevated security context, which could result in privilege escalation beyond the attacker's granted permissions.
