CVE-2025-9734Public exploitNetwork attack vector

Stored script execution via unsanitized profile fields

Published Aug 31, 2025 · Updated Sep 2, 2025

Stored cross-site scripting in O2OA 10.0-410 and earlier allows remote authenticated users to execute JavaScript in viewers' browsers. The stat endpoint stores the name, alias, description, and applicationName fields without sanitization and later renders them as page content. Attackers need authenticated access to save a profile, and execution occurs when another user views it, enabling actions in that user's session.
