Stored script execution via unsanitized profile description

Published Aug 29, 2025 · Updated Aug 29, 2025

Stored XSS in O2OA 10.0-410 allows remote authenticated users to execute JavaScript in browsers that view a crafted profile. The person profile endpoint stores the Description field without sanitization and later renders it as active markup. An authenticated account must update a profile, and another user must view it; the script then acts in that viewer's session.
