Background

The 'established_baboon-teagooddev' package is part of a series of npm packages associated with the tea.xyz token reward campaign. These packages are designed to inflate developer reputation scores by automatically generating and publishing derivative packages with randomized names. The functionality of these packages is compromised due to the presence of malicious scripts that manipulate package metadata.

Vulnerability Detail

This vulnerability originates from the malicious code embedded within the 'established_baboon-teagooddev' package. The code modifies the package.json file to remove private flags, alters version numbers, and generates random package names, which leads to the continuous republishing of these variants. This behavior not only pollutes the npm registry but also poses a risk to developers who may unknowingly use these compromised packages, potentially leading to security breaches and loss of trust in the npm ecosystem.

How To Fix

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

npm uninstall established_baboon-teagooddev

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