Background

teagood-cuekin94 is an npm package that is part of the tea.xyz token reward campaign. This package is designed to facilitate the generation and publication of derivative packages with randomized names. The primary function of this package is to inflate developer reputation scores for tea protocol token rewards, but it has been compromised to include malicious scripts that can alter package metadata.

Vulnerability Detail

The vulnerability in teagood-cuekin94 stems from its inclusion in a malicious campaign that modifies the package.json file to remove private flags and change version numbers. It generates random package names and continuously republishes variants, which pollutes the npm registry. This can lead to unauthorized access to sensitive data, reputation damage for developers, and a compromised npm ecosystem.

How To Fix

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

npm uninstall teagood-cuekin94

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