Background

The emmahayes package is part of the npm ecosystem, which is widely used for JavaScript package management. It is designed to facilitate the development and sharing of JavaScript code. However, this package has been identified as part of a malicious campaign that aims to inflate developer reputation scores through the automatic generation and publication of derivative packages. This behavior poses a significant risk to developers and users relying on the integrity of npm packages.

Vulnerability Detail

The vulnerability in the emmahayes package originates from its association with the tea.xyz token reward campaign. The package contains malicious scripts that modify the package.json file by removing private flags, altering version numbers, and generating random package names. This leads to the continuous republishing of these variants, which pollutes the npm registry and compromises the security of the ecosystem. The ramifications include potential exposure to further malicious code and a degradation of trust in the npm registry.

How To Fix

This package is malicious. Remove it and rotate any credentials it could have accessed.

npm uninstall emmahayes

If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
