CVE-2026-85967
MediumCVSS 6.1Summary
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.
Risk Assessment
An attacker can hijack a logged-in user's session, perform actions on their behalf, or exfiltrate sensitive data.
Recommendation
Upgrade MarkLogic Server to 12.1.0 or 11.3.7 immediately, and apply XSS protections such as input validation and output encoding.
Other vulnerabilities in MarkLogic Server
See all- CVE-2026-85976Medium
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.
- 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.
