CVE-2026-85952

Progress MarkLogic Server versions before 12.1.0 (12.x) and before 11.3.7 (11.x) fail to sanitize input used by the Query Console file-exploration endpoint, allowing HTTP response splitting and unintended client-side response handling.

Progress MarkLogic Server before 12.1.0 (12.x) and 11.3.7 (11.x) contains a cross-site scripting vulnerability that allows a remote attacker to execute script in the context of an authenticated user's browser session, leading to unauthorized actions or information disclosure.

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.

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.

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 on Azure contain a server-side request forgery vulnerability that could allow an authenticated attacker to access internal cloud services, potentially resulting in unauthorized access to cloud credentials or tokens.
