Summary

When the optional Chrome extension relay is enabled, /extension accepted unauthenticated WebSocket upgrades while /json/* and /cdp required auth.

Affected Packages / Versions

Package: openclaw (npm)
Affected: <= 2026.2.17
Latest published npm version at triage time: 2026.2.17

Impact

This is a local-only issue on loopback (127.0.0.1) and only applies when the extension relay feature is in use. A local process on the same machine could connect to /extension without the token and interfere with extension-relay behavior.

No remote network exploit path is involved.

Fix

Require gateway-token auth on both /extension and /cdp relay WebSocket endpoints.
Keep loopback/origin checks as defense-in-depth, not as authentication.
Use one token path in setup: gateway.auth.token / OPENCLAW_GATEWAY_TOKEN.
