CVE-2025-10211Public exploitNetwork attack vector

Authenticated SSRF via unrestricted taskUrl requests

Published Sep 10, 2025 · Updated Sep 10, 2025

Server-side request forgery in ChanCMS 3.3.0 allows remote authenticated users to make server-side requests via a crafted taskUrl. CollectController accepts taskUrl at /cms/collect/getArticle and uses it as an outbound-request destination without restricting the target. Low-privileged network access is required; successful exploitation reaches network resources available to the ChanCMS server.
