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.
