Stored script execution via unsanitized form metadata
Published Aug 31, 2025 · Updated Sep 2, 2025
Stored XSS in O2OA 10.0-410 allows remote authenticated users to execute scripts in other users' browsers via crafted form metadata. The form endpoint stores name, alias, description, category, and embedded form JSON without sanitization, then renders those values as HTML. An authenticated form designer must save the payload and another user must view the profile; exploitation runs attacker-supplied JavaScript in that user's session.
