CVE-2026-30819Network attack vector

Script execution via unsanitized dashboard identifier

Published Aug 21, 2026 · Updated Aug 21, 2026

Reflected XSS in Combodo iTop before 3.2.3 allows remote authenticated users to execute scripts in a victim's browser via dashboard reversion. In pages/ajax.render.php, revert_dashboard accepted dashboard_id as raw data and embedded it in generated JavaScript; the patch applies a context-parameter filter before JSON encoding. Exploitation requires a low-privilege iTop account and user interaction, and successful script execution can read or alter iTop data accessible to the victim.
