CVE-2026-102095

Kiteworks Email Protection Gateway before version 9.5.0 is vulnerable to Server-Side Request Forgery. Kiteworks Email Protection Gateway performed server-side fetches of URLs contained in the message content it processed, without adequately restricting the fetch destination. A remote, unauthenticated sender could craft a message that caused the gateway to issue requests to internal services and cloud instance metadata endpoints and return the responses, potentially disclosing sensitive internal data and, depending on the internal service reached, affecting its state.
