Description

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.

CVE-2026-102149
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.

CVE-2026-102147
A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an unauthenticated attacker to store crafted content that later executes arbitrary JavaScript in the authenticated session of an administrator who views the affected page. This could have permitted the attacker to gain full administrative control, including the creation of a new administrative account.

CVE-2026-102115
Kiteworks Core did not correctly validate a parameter submitted to the password reset workflow. An unauthenticated attacker who knew the email address of a user with a locally stored password could potentially reset that account's password without access to the emailed reset link and then authenticate as that user, including where the account holds administrative privileges.

CVE-2026-102106
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.

CVE-2026-102105
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.
