Title

OpenClaw服务器端请求伪造漏洞（CNVD-2026-39817）

Description

OpenClaw是一款由奥地利开发者彼得·斯坦伯格创建的开源AI智能体。 OpenClaw存在服务器端请求伪造漏洞，该漏洞源于Synology Chat附件传递过程中DNS绑定失效，网关仅验证单个DNS结果后将原始主机名传递给Synology NAS，攻击者可利用该漏洞通过DNS重绑定使网络附加存储获取本应被策略禁止的私有资源，并将响应内容返回到会话中。

CVE-2026-100555 (GCVE-0-2026-100555)

Vulnerability from cvelistv5 – Published: 2026-09-26 02:18 – Updated: 2026-10-05 14:55

Title

OpenClaw before 2026.8.1 DNS Rebinding via attachment delivery

Summary

OpenClaw is an npm-distributed gateway application. In versions >= 2026.7.1 and < 2026.8.1, Synology Chat attachment delivery could lose DNS pinning: the Gateway validated a single DNS result for a supplied file URL but then passed the original hostname to the Synology NAS, where it could resolve to a different destination. When attachment delivery accepted a remotely influenced hostname, an attacker could use DNS rebinding to make the NAS fetch a private or otherwise policy-denied resource and return its contents to the addressed conversation (server-side request forgery). Practical impact depends on NAS routing, resolver behavior, and the response available at the private destination. The issue is fixed in 2026.8.1; as a workaround, disable remote URL attachment forwarding in Synology Chat.
