CVE-2026-85967Network attack vectorHinoki check available

Browser-session script execution

Published Oct 12, 2026 · Updated Oct 12, 2026

Cross-site scripting in Progress MarkLogic Server allows remote attackers to execute script in authenticated browser sessions. For 11.x before 11.3.7 and 12.x before 12.1.0, the retrieved public record does not identify the affected component or faulty input-handling operation. Exploitation requires user interaction and an authenticated browser session; unauthorized actions and disclosure are bounded by that user's accessible information and permissions.
