Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenClaw 是一款通过 npm 分发的网关应用程序。在版本 >= 2026.7.1 且 < 2026.8.1 中，Synology Chat 的附件传递功能存在 DNS 固定（DNS pinning）丢失的问题：网关虽对所提供的文件 URL 仅验证了一个 DNS 解析结果，但随后却将原始主机名传递给 Synology NAS，导致该主机名可能解析到不同的目标地址。当附件传递功能接受了由远程影响的主机名时，攻击者可利用 DNS 重绑定（DNS rebinding）技术，诱导 NAS 获取私有资源或策略禁止访问的

Vulnerability Title
OpenClaw before 2026.8.1 DNS Rebinding via attachment delivery
Source: CVE Program / CVE List V5
Vulnerability Description
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.
