CVE-2026-53814Network attack vector

Privilege escalation via owner-scoped hook authority

Published Jun 11, 2026 · Updated Jun 11, 2026

Privilege escalation in OpenClaw before 2026.5.20 allows remote authenticated users to invoke owner-only MCP tools through /hooks/agent. Hook ingress passes a hook-triggered bundled CLI runtime owner-scoped MCP loopback authority instead of the restricted scope assigned to hook automation. Reachability requires enabled hooks, a valid hook token, a reachable endpoint, and a selectable bundled CLI backend; exposed tools determine the privileged actions, including persistent cron-state changes.
