How to Fix CVE-2026-53812

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.

openclaw fixed: 2026.5.18 
npm install openclaw@2026.5.18
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls openclaw

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-53812, inspect your project dependencies using npm:

npm ls openclaw

Analyze 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 2026.5.18), 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-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource 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.

Source Advisory Statement

### Summary OpenClaw's browser control SSRF checks blocked direct navigation to private or loopback URLs, but some Playwright `act` interactions could trigger navigation after the initial check. A later browser evaluation could then read from the page reached by that action-triggered navigation. This issue is specific to browser control actions and private-network navigation policy. Browser evaluation remains an intentional trusted-operator feature when it is used on pages that policy allowed the browser to visit. ### Affected configurations This affects deployments where browser control is enabled and an authenticated browser-control caller can interact with an attacker-controlled page that redirects or navigates the tab to a private-network target through a UI action. ### Impact If the browser reached a private page through an unchecked action-triggered navigation, a caller with browser evaluation capability could read page content that direct navigation policy would have blocked. The issue does not grant access to OpenClaw without authentication. It bypasses the private-network navigation guard for a specific browser action path. ### Patched Versions The first stable patched version is `2026.5.18`. ### Mitigations Upgrade to `openclaw@2026.5.18` or later. Before upgrading, restrict browser-control access to trusted operators and avoid using browser control on untrusted pages in environments with sensitive private web services.
