CVE-2026-45005Network attack vector

Continued webhook access via stale secret cache

Published May 11, 2026 · Updated May 11, 2026

Authentication bypass in OpenClaw before 2026.4.23 allows remote authenticated users to invoke webhook task flows with a stale route secret. The task-flow webhook handler in extensions/webhooks/src/http.ts stores each resolved SecretRef value in a WeakMap instead of resolving it for every request. Exploitation requires a previously valid route secret and a rotation followed by secrets reload; access persists only until the gateway or plugin restarts.
