CVE-2025-9657Public exploitNetwork attack vector

Stored XSS via unsanitized script metadata

Published Aug 29, 2025 · Updated Aug 29, 2025

Stored XSS in O2OA 10.0-410 allows remote authenticated users to execute JavaScript in a victim's browser through crafted script metadata. The /x_program_center/jaxrs/script endpoint stores unsanitized name, alias, and description values that the Personal Profile page later renders as active HTML. An authenticated user must save a payload and a victim must view the affected profile, enabling browser-context actions and access to data available to that session.
