HIGH 7.7

Published 2026-10-12 · Last modified 2026-10-15

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 do not sufficiently restrict access to certain security-sensitive information. A remote authenticated attacker with limited management permissions could obtain this information, which could result in unauthorized access to protected resources.
