CVE-2026-30865Network attack vector

Browser script execution via unencoded dashboard parameters

Published Aug 21, 2026 · Updated Aug 21, 2026

Reflected XSS in Combodo iTop before 3.2.3 allows remote attackers to execute script in a user's browser through dashboard saving. In pages/ajax.render.php, dashboard_id and reload_url values are interpolated into generated JavaScript string literals without JSON encoding. A target must load the attacker-controlled response; the script then runs in the iTop origin and can act with that user's browser privileges.
