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-290: Authentication Bypass by Spoofing, where this attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.

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## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-mp66-rf4f-mhh8. This link is maintained to preserve external references. ## Original Description OpenClaw before 2026.3.22 contains an improper authentication verification vulnerability in Google Chat app-url webhook handling that accepts add-on principals outside intended deployment bindings. Attackers can bypass webhook authentication by providing non-deployment add-on principals to execute unauthorized actions through the Google Chat integration.
