{"id":"CVE-2026-100572","published":"2026-09-26T03:17:04.570","lastModified":"2026-09-28T15:18:41.260","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.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","cwes":["CWE-400"],"vendors":[],"products":[],"references":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-fw6q-2frm-jxxr","tags":[]},{"url":"https://www.vulncheck.com/advisories/openclaw-before-2026.8.1-denial-of-service-via-rate-limit","tags":[]}],"exploitRefs":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-fw6q-2frm-jxxr","tags":[]}],"hasPoc":true,"ai":null}
