CVE-2026-102105 (GCVE-0-2026-102105)

Vulnerability from cvelistv5 – Published: 2026-09-30 20:25 – Updated: 2026-10-01 13:37

Title
Kiteworks Email Protection Gateway server-side request forgery
Summary
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 (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 performs an online certificate status check for an inbound message. Depending on the services reachable from the gateway, this could disclose sensitive internal information or disrupt gateway operation.

CVE-2026-102103 (GCVE-0-2026-102103)

Vulnerability from cvelistv5 – Published: 2026-09-30 20:16 – Updated: 2026-10-01 13:37

Title
Kiteworks Email Protection Gateway server-side request forgery
Summary
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 retrieves a certificate revocation list in an inbound message. Depending on the services reachable from the gateway, this could disclose sensitive internal information or disrupt gateway operation.

Title
Kiteworks Email Protection Gateway server-side request forgery
Summary
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.

Title
Kiteworks Secure Data Forms server-side request forgery
Summary
Kiteworks Secure Data Forms before version 9.5.0 is vulnerable to Server-Side Request Forgery that could allow an unauthenticated, remote attacker to make the server issue arbitrary outbound network requests and read back the responses. This could potentially be used to reach internal-only services or other network-restricted resources.

CVE-2026-101913 (GCVE-0-2026-101913)

Vulnerability from cvelistv5 – Published: 2026-09-28 17:49 – Updated: 2026-09-28 18:38
VLAI
Title
ip-address: Address6.isLinkLocal() recognizes fe80::/64 rather than fe80::/10, allowing SSRF and trust-boundary bypass to on-link hosts
Summary
ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.5.1, the Address6 isLinkLocal method in src/ipv6.ts recognizes only fe80::/64 instead of the complete fe80::/10 IPv6 link-local range. An attacker-controlled address elsewhere in fe80::/10 can therefore pass a trust-boundary check that relies on isLinkLocal. The same address is identified as link-local by getType and getScope, exposing the inconsistent classification. A successful bypass can reach an on-link host outside the intended trust boundary. This issue is fixed in version 10.5.1.

CVE-2026-101910 (GCVE-0-2026-101910)

Vulnerability from cvelistv5 – Published: 2026-09-28 17:45 – Updated: 2026-09-28 18:12

Title
ip-address: no classifier recognizes the NAT64 local-use range 64:ff9b:1::/48, allowing SSRF and trust-boundary bypass
Summary
ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. From 10.2.0 until 10.5.1, the Address6 isPrivate classifier in src/ipv6.ts does not recognize the NAT64 local-use range 64:ff9b:1::/48. Applications that combine isPrivate, isLoopback, and isLinkLocal for a trust-boundary decision can treat an internal IPv4 destination encoded through that range as external. Exploitation depends on a server network using an operator-selected NAT64 prefix within the local-use range. A successful bypass can cross the intended network trust boundary. This issue is fixed in version 10.5.1.

CAPEC-664: Server Side Request Forgery

An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
