CVE-2026-85976
MediumCVSS 5.4Summary
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.
Risk Assessment
This vulnerability could be exploited to manipulate HTTP responses, potentially leading to cache poisoning, open redirects, or malicious script execution in the victim's browser.
Recommendation
Upgrade MarkLogic Server to 12.1.0 or 11.3.7 or later, and implement input validation and output encoding in the application layer.

See all- CVE-2026-85967Medium
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.
- CVE-2026-85954High
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.
- CVE-2026-85953High
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.
- CVE-2026-85952High
Affected Linux-based Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 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.
- CVE-2026-85951High
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.
