Recommendation: Monitor — no exploitation signal at the moment.

OpenClaw before 2026.5.18 accepts WebSocket client-declared operator scopes before binding to server-approved pairing or trusted-proxy authorization baseline. Unpaired or restricted trusted-proxy Control UI clients can obtain cached operator.admin authority on live WebSocket connections to execute admin-gated Gateway RPCs.
