Background

teagood-manaki88 is an npm package that is part of a broader campaign associated with the tea.xyz token reward system. This package, like others in the campaign, is designed to manipulate the npm registry by automatically generating and publishing derivative packages. The primary functionality of this package is to inflate developer reputation scores through the creation of numerous random package names, which can lead to significant pollution of the npm ecosystem.

Vulnerability Detail

The vulnerability in teagood-manaki88 stems from its malicious code that modifies the package.json file to remove private flags and alters version numbers. It generates random package names, primarily themed around Indonesian culture, and continuously republishes these variants. This behavior not only compromises the integrity of the npm registry but also poses risks to developers who may unknowingly install these malicious packages, potentially leading to security breaches in their applications.

How To Fix

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

npm uninstall teagood-manaki88

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