Background
The @insiderintelligence/componentlibrary is an npm package designed to provide a set of components for building user interfaces. It is widely used in web development for its reusable components and ease of integration. However, a serious vulnerability has been identified that allows malicious code to be executed during the installation process, compromising user data and system integrity.
Vulnerability Detail
The vulnerability arises from the package's installation script, which automatically executes 'node index.js' during npm install. This script loads a module that collects sensitive information such as the username, hostname, and current working directory, and sends this data to a remote server via a DNS query. This behavior is hidden through obfuscation techniques, making it difficult to detect. The malicious code bypasses HTTP egress controls, posing significant risks to user privacy and security.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall @insiderintelligence/componentlibraryIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
