CVE-2022-38550Network attack vector

Stored script execution via crafted list content

Published Sep 19, 2022 · Updated May 27, 2025

Stored XSS in the /weibo/list component of Jeesns 2.0.0 allows remote authenticated users to execute scripts in another user's browser. The public disclosure identifies a crafted payload reaching /weibo/list but does not identify the affected parameter, storage path, rendering sink, or missing output-encoding operation. Exploitation requires low-privileged access to store content and a user to view the affected list; script execution is limited to the viewer's web context.
