Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenClaw 版本 2026.3.25 及更高版本但低于 2026.8.1 存在以下问题：对于 Synology Chat Webhook 请求，系统在认证之前即应用了“无效令牌速率限制”，并且该限制以原始代理套接字地址作为键进行计数。 在 OpenClaw 部署于可信反向代理或隧道之后，且多个外部客户端共享同一套接字地址的场景下，未认证的发送方可以耗尽共享的无效令牌配额，导致后续的合法 Synology Chat Webhook 回调请求被拒绝，直至速率限制窗口结束。攻击者无法获取有效令牌或读取消息数据；其影

Vulnerability Title
OpenClaw before 2026.8.1 Denial of Service via Rate Limit
Source: CVE Program / CVE List V5
Vulnerability Description
OpenClaw versions >= 2026.3.25 and < 2026.8.1 apply invalid-token rate limiting for Synology Chat webhooks before authentication and key the limit on the raw proxy socket address. In deployments where OpenClaw sits behind a trusted reverse proxy or tunnel and multiple external clients share a single socket address, an unauthenticated sender can exhaust the shared invalid-token budget, causing subsequent legitimate Synology Chat webhook callbacks to be rejected until the rate-limit window expires. The attacker cannot obtain a valid token or read message data; the impact is temporary loss of channel availability. Fixed in 2026.8.1.
