Sep 30, 2026Kiteworks Email Protection Gateway did not sufficiently restrict which account a certificate could be assigned to.CVE-2026-102149 · Other software · Kiteworks · reported by 9119a7d8-5eab-497f-8521-727c672e3725Critical 9.4
Kiteworks Email Protection Gateway did not sufficiently restrict which account a certificate could be assigned to. This could allow an attacker to associate a certificate with another user's account, affecting the confidentiality and integrity of that account's encrypted mail and, where certificate-based login is enabled, potentially permitting unauthorized access to the account.

An unauthenticated attacker could cause a file with attacker-controlled content to be written to the appliance filesystem through an administrative upload handler that did not properly authenticate the request. This did not by itself result in code execution, which would require a separate vulnerability to place the file in an executable location.

On a Kiteworks Email Protection Gateway cluster with database replication enabled, a party trusted by the cluster could submit a crafted serialized object that was deserialized without sufficient validation, potentially allowing code execution as the gateway service account. Replication is disabled by default, and exploitation requires control of a trusted cluster peer or administrative access to the appliance.

An identity-verification weakness in Kiteworks Email Protection Gateway allowed the gateway to act on the Kiteworks platform on behalf of a user it had not authenticated, and to provision a platform account for an identity it did not already know. A remote, unauthenticated sender could potentially exploit this to obtain control of a platform account.

Improper authentication in a Kiteworks Email Protection Gateway administrative service. An administrative service in Kiteworks Email Protection Gateway did not consistently enforce administrator authentication, so the required password check could be bypassed. An attacker who referenced a valid administrator account could potentially create, modify, or delete internal users and managed domains and change their security-feature configuration without authenticating; deleting a managed domain also removes its user accounts and could lock administrators out of the gateway.

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.

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.
