CVE-2026-100572

OpenClaw before 2026.8.1 Denial of Service via Rate Limit

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.
