How to Fix GHSA-27pq-2ph8-8x25

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-27pq-2ph8-8x25, 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-184: Incomplete List of Disallowed Inputs, where the product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete. 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## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-5cj2-3jr2-5h77. This link is maintained to preserve external references. ## Original Description OpenClaw before 2026.4.2 contains an inline-eval bypass vulnerability allowing authenticated operators to weaken strict allowlist checks via shell positional parameters. Attackers can combine allowlisted tools with shell positional arguments to place inline-eval content in shell carriers outside intended allowlist rules, enabling execution of unapproved shell-provided content.
