CVE-2026-102095— Kiteworks Email Protection Gateway server-side request forgery

一分钟漏洞结论

影响对象
Kiteworks Email Protection Gateway
利用判断
尚无明确在野利用证据，仍需结合暴露面评估
建议动作
优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。

Kiteworks 邮件防护网关（Email Protection Gateway）在 9.5.0 版本之前存在服务器端请求伪造（SSRF，Server-Side Request Forgery）漏洞。该网关在处理邮件内容时，会对其中包含的 URL 执行服务器端抓取操作，但未对抓取目标进行充分限制。远程未认证的攻击者可以构造特定邮件，诱使网关向内部服务或云实例元数据端点发起请求并返回响应，从而可能泄露敏感的内部数据；此外，根据所访问的内部服务不同，还可能影响其状态。

Vulnerability Title
Kiteworks Email Protection Gateway server-side request forgery
来源: CVE Program / CVE List V5
Vulnerability 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.
