Background

The muny-bopaha-reasz package is part of the npm ecosystem, which is widely used for JavaScript package management. This package has been identified as part of a malicious campaign targeting the npm registry, specifically designed to inflate developer reputation scores through the generation of derivative packages. The malicious nature of this package compromises the integrity of the npm ecosystem by introducing harmful scripts.

Vulnerability Detail

The vulnerability in the muny-bopaha-reasz package originates from its association with the tea.xyz token reward campaign. It contains scripts that automatically modify the package.json file to remove private flags, alter version numbers, and generate random package names. This behavior leads to the continuous republishing of variants, polluting the npm registry and potentially compromising other packages and applications that rely on npm.

How To Fix

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

npm uninstall muny-bopaha-reasz

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