Background
teagood-manaki80 is an npm package that is part of a token reward campaign associated with the tea.xyz protocol. This package is designed to incentivize developers through rewards, but it has been compromised to include malicious scripts that manipulate package metadata. The vulnerability stems from the package's functionality, which is intended to publish derivative packages, but has been exploited to generate harmful variants that can pollute the npm registry.
Vulnerability Detail
The vulnerability in teagood-manaki80 originates from its inclusion in a campaign that floods the npm ecosystem with malicious packages. The package contains scripts that automatically modify the package.json file to remove private flags, alter version numbers, and create random package names. This behavior not only inflates developer reputation scores but also leads to the continuous republishing of these malicious variants, posing a significant risk to the integrity of the npm registry and potentially affecting users who unknowingly install these compromised packages.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall teagood-manaki80
If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
