Stored XSS via unsandboxed inline HTML attachments
Published Apr 5, 2022 · Updated Apr 22, 2025
Stored cross-site scripting in Combodo iTop before 2.7.6 allows remote authenticated users to run script in a user's browser via HTML attachments. The DocumentAction and ajax.render.php inline response paths return attacker-controlled HTML without a Content-Security-Policy sandbox. An attacker must be able to add an HTML attachment, and a logged-in user must display it; resulting script runs in the iTop origin and can read or alter data available to that user.
