openclaw fixed: 2026.1.29 
npm install openclaw@2026.1.29
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-2026-6011, 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 2026.1.29), 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-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. 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

A weakness has been identified in OpenClaw up to 2026.1.26. Affected by this issue is some unknown functionality of the file src/agents/tools/web-fetch.ts of the component assertPublicHostname Handler. Executing a manipulation can lead to server-side request forgery. The attack can be executed remotely. This attack is characterized by high complexity. The exploitation is known to be difficult. The exploit has been made available to the public and could be used for attacks. Upgrading to version 2026.1.29 can resolve this issue. This patch is called b623557a2ec7e271bda003eb3ac33fbb2e218505. Upgrading the affected component is advised.
