What it is
From the CVE record
Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 contain privileged legacy InfoStudio modules that do not sufficiently validate user-controlled file paths and user-context values. Exploitation could result in unauthorized access to server files or execution under an unintended identity.
