CVE-2026-102105

critical

Kiteworks Email Protection Gateway before version 9.5.0 is vulnerable to Server-Side Request Forgery (SSRF).

Vendor / product: Accellion — kiteworks

Kiteworks Email Protection Gateway before version 9.5.0 is vulnerable to Server-Side Request Forgery (SSRF). A server-side request forgery (SSRF) weakness in Kiteworks Email Protection Gateway could allow a remote, unauthenticated attacker to induce the gateway to issue crafted requests to internal or otherwise unintended network destinations. The requests are triggered while the gateway renders message content that references external resources. Depending on the services reachable from the gateway, this could disclose sensitive internal information or trigger unintended actions on internal systems.
