Description

OpenClaw's Trusted-proxy Control UI sessions retain privileged scopes without device identity on device-less allow paths

Summary

Trusted-proxy Control UI sessions without device identity could retain self-declared privileged scopes on the device-less allow path.

Release Status

The fix shipped in v2026.3.22 and remains present in v2026.3.23 and v2026.3.23-2.

Code-Level Confirmation

  • src/gateway/server/ws-connection/message-handler.ts now strips unbound self-declared scopes on the trusted-proxy no-device path.
  • src/gateway/server/ws-connection/connect-policy.ts remains the allow path, but the shipped scope scrub prevents privilege retention without device identity.

OpenClaw thanks @nexrin for reporting.
