How to Fix GHSA-8px5-2gfr-7ph6

To remediate this vulnerability, upgrade all affected Duplicate Advisory 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: Latest secure release 
npm install openclaw@Latest secure release
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 GHSA-8px5-2gfr-7ph6, inspect your project dependencies using npm:

npm ls openclaw

Analyze the terminal output to locate any version of Duplicate Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), 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-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Duplicate Advisory, 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

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-fg3m-vhrr-8gj6. This link is maintained to preserve external references. ## Original Description OpenClaw versions 2026.1.21 prior to 2026.2.19 contain a command injection vulnerability in the Lobster extension's Windows shell fallback mechanism that allows attackers to inject arbitrary commands through tool-provided arguments. When spawn failures trigger shell fallback with shell: true, attackers can exploit cmd.exe command interpretation to execute malicious commands by controlling workflow arguments.
