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 do not sufficiently sanitize input used by the Query Console file-exploration endpoint, which could allow HTTP response splitting and unintended client-side response handling.
