CVE-2025-5005Public exploitNetwork attack vector

Unauthenticated server-side requests via unvalidated corpurl redirect

Published Sep 9, 2025 · Updated Sep 9, 2025

Server-side request forgery in Lingdang CRM 8.6.5.0 through 8.6.5.4 allows remote attackers to send server-originated requests via corpurl. The endpoint reads corpurl directly from the HTTP request and forms a redirect Location value without destination validation; no downstream fetch routine is disclosed. The endpoint requires no authentication, and the published test uses an external DNS-logging host; response disclosure or internal data access is not demonstrated.
