How to Fix GHSA-g6f4-j6c2-w3p3

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

uglify-js fixed: 2.4.24 
npm install uglify-js@2.4.24
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 uglify-js

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-g6f4-j6c2-w3p3, inspect your project dependencies using npm:

npm ls uglify-js

Analyze the terminal output to locate any version of Uglify js in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.4.24), your application is affected.

Note: The npm ls uglify-js 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 Uglify js, 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

Withdrawn, accidental duplicate publish. The uglify-js package before 2.4.24 for Node.js does not properly account for non-boolean values when rewriting boolean expressions, which might allow attackers to bypass security mechanisms or possibly have unspecified other impact by leveraging improperly rewritten Javascript.
