Background

The confused_rattlesnake-teagooddev package is part of the npm ecosystem and is associated with the tea.xyz token reward campaign. This package is designed to facilitate the automatic generation and publication of derivative packages, which can inflate developer reputation scores in exchange for tea protocol token rewards. However, it has been identified as containing malicious code that compromises the integrity of the npm registry.

Vulnerability Detail

The vulnerability originates from the package's malicious payload, which modifies the package.json file to remove private flags, alters version numbers, and generates random package names. This behavior leads to the continuous republishing of variants that pollute the npm registry, potentially affecting other developers and users by introducing untrusted code into their projects.

How To Fix

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

npm uninstall confused_rattlesnake-teagooddev

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