How to Fix CVE-2026-22174
To remediate this vulnerability, upgrade all affected Openclaw dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install openclaw@2026.2.22Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls openclawHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2026-22174, inspect your project dependencies using npm:
npm ls openclawAnalyze the terminal output to locate any version of Openclaw in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2026.2.22), your application is affected.
Note: The npm ls openclaw command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

"details" : "### Summary\nA local process can capture the OpenClaw Gateway auth token from Chrome CDP probe traffic on loopback.\n\n### Details\nAffected versions inject `x-openclaw-relay-token` for loopback CDP URLs, and CDP reachability probes send that header to `/json/version`.\nIf an attacker controls the probed loopback port, they can read that token and reuse it as Gateway bearer auth.\n\nRelevant code paths (pre-fix):\n- `src/browser/extension-relay.ts` (`getChromeExtensionRelayAuthHeaders`)\n- `src/browser/cdp.helpers.ts` (`getHeadersWithAuth`)\n- `src/browser/chrome.ts` (`fetchChromeVersion`)\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Latest published (at triage): `2026.2.21-2`\n- Vulnerable: `<= 2026.2.21-2`\n- Patched: >= 2026.2.22\n\n### Deployment Model Applicability\nThis 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).\nRisk is for **non-standard shared-user/shared-host installs** where an untrusted local user/process can race/bind the loopback relay port.\n\n### Impact\n- Local credential disclosure.\n- Follow-on impact depends on local deployment and enabled Gateway capabilities.\n\n### Fix Commit(s)\n- `afa22acc4a09fdf32be8a167ae216bee85c30dad`\n\n### Release Process Note\nPatched version is set to >= 2026.2.22 for the published release.\n\nOpenClaw thanks @tdjackey for reporting.",
