How to Fix GHSA-9xww-fwh9-95c5

To remediate this vulnerability, upgrade all affected Uglyfi 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.

npm install uglyfi-js@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 uglyfi-js

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-9xww-fwh9-95c5, inspect your project dependencies using npm:

npm ls uglyfi-js

Analyze the terminal output to locate any version of Uglyfi js 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 uglyfi-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 CWE-506: Embedded Malicious Code, where the product contains code that appears to be malicious in nature. In Uglyfi 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

Version 3.4.6 of `uglyfi-js` contains malicious code as a preinstall script. The package is malware designed to take advantage of users making a mistake when typing the name of a module to install. When installed, the package downloads a file from a remote server, executes it and opens a backdoor. ## Recommendation Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
