CVE-2025-6762Public exploitNetwork attack vector

Authenticated SSRF via unvalidated Host header

Published Jun 27, 2025 · Updated Jun 27, 2025

Server-side request forgery in diyhi 巡云轻论坛 6.0 through 6.8 allows remote authenticated users to redirect backend login requests. The /admin/login handler passes the request to Configuration.getUrl, which builds the OAuth target from request.getServerName without validating the Host-derived hostname and port. Administrative login credentials are required, and exploitation forces a server-originated POST to an attacker-chosen or otherwise unauthorized service.
