Summary

A local process can capture the OpenClaw Gateway auth token from Chrome CDP probe traffic on loopback.

Details

Affected versions inject x-openclaw-relay-token for loopback CDP URLs, and CDP reachability probes send that header to /json/version. If an attacker controls the probed loopback port, they can read that token and reuse it as Gateway bearer auth.
Relevant code paths (pre-fix):
  • src/browser/extension-relay.ts (getChromeExtensionRelayAuthHeaders)
  • src/browser/cdp.helpers.ts (getHeadersWithAuth)
  • src/browser/chrome.ts (fetchChromeVersion)

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published (at triage): 2026.2.21-2
  • Vulnerable: <= 2026.2.21-2
  • Patched: >= 2026.2.22

Deployment Model Applicability

This does not change OpenClaw’s documented security model for standard single-owner installs (you own the machine/VPS and trust local processes under that OS account boundary). Risk is for non-standard shared-user/shared-host installs where an untrusted local user/process can race/bind the loopback relay port.

Impact

  • Local credential disclosure.
  • Follow-on impact depends on local deployment and enabled Gateway capabilities.
