CVE-2026-31880Network attack vector

Authenticated script execution via reflected OQL errors

Published Aug 21, 2026 · Updated Aug 21, 2026

Reflected XSS in Combodo iTop before 3.2.3 allows remote authenticated users to execute script through universal-search requests. The search_oql handler in pages/UI.php accepts the oql_clause parameter as raw data, incorporates it into an OQL query, and returns parser-error HTML without encoding attacker-controlled markup. Low-privileged access and interaction by another user are required; opening a crafted search URL runs the injected script in that user's browser context.
