Security Impact
CVSS: 7.1
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L).
How to Fix CVE-2026-26317
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@2026.2.14npm install clawdbot@Latest secure releaseRun 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-2026-26317, 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 2026.2.14), 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.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Openclaw, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "## Summary\nBrowser-facing localhost mutation routes accepted cross-origin browser requests without explicit Origin/Referer validation. Loopback binding reduces remote exposure but does not prevent browser-initiated requests from malicious origins.\n\n## Impact\nA malicious website can trigger unauthorized state changes against a victim's local OpenClaw browser control plane (for example opening tabs, starting/stopping the browser, mutating storage/cookies) if the browser control service is reachable on loopback in the victim's browser context.\n\n## Affected Packages / Versions\n- openclaw (npm): <= 2026.2.13\n- clawdbot (npm): <= 2026.1.24-3\n\n## Details\nThe browser control servers bind to loopback but exposed mutating HTTP endpoints without a CSRF-style guard. Browsers may send cross-origin requests to loopback addresses; without explicit validation, state-changing operations could be triggered from a non-loopback Origin/Referer.\n\n## Fix\nMutating HTTP methods (POST/PUT/PATCH/DELETE) are rejected when the request indicates a non-loopback Origin/Referer (or `Sec-Fetch-Site: cross-site`).\n\n## Fix Commit(s)\n- openclaw/openclaw: b566b09f81e2b704bf9398d8d97d5f7a90aa94c3\n\n## Workarounds / Mitigations\n- Enable browser control auth (token/password) and avoid running with auth disabled.\n- Upgrade to a release that includes the fix.\n\n## Credits\n- Reporter: @vincentkoc\n\n## Release Process Note\n`patched_versions` is set to the planned next release version.
