OpenClaw has auth inconsistency on local Browser Extension Relay /extension endpoint
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
/extensionand/cdprelay 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.
