CVE-2026-9195 is a cross-site scripting vulnerability in the Query Console component of Progress MarkLogic Server. It affects MarkLogic Server 11.x before 11.3.6 and 12.x before 12.0.3. The flaw can be triggered when a remote attacker induces an authenticated administrator to visit a crafted URL, resulting in arbitrary JavaScript execution within the administrator's browser session in the context of the Query Console. This can expose administrator session data and enable actions to be performed through the administrator's authenticated context.
