How to Fix GHSA-54qm-37qr-w5wq

To remediate this vulnerability, upgrade all affected Veval dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

veval fixed: Latest secure release 
npm install veval@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 veval

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-54qm-37qr-w5wq, inspect your project dependencies using npm:

npm ls veval

Analyze the terminal output to locate any version of Veval 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 veval 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 General Security Weakness. In Veval, 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

All versions of `veval` are vulnerable to Sandbox Escape leading to Remote Code Execution. The package fails to restrict access to the main context through `this.constructor.constructor` . This may allow attackers to execute arbitrary code in the system. Evaluating the payload `this.constructor.constructor('return process.env')()` prints the contents of `process.env`. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available.
