Background
teagood-cuekin60 is an npm package that is part of the tea.xyz token reward campaign. This package is designed to interact with the npm registry, potentially inflating developer reputation scores through automated publishing. However, it has been identified as containing malicious code that modifies its own package.json file and publishes harmful variants, posing a significant risk to users and the integrity of the npm ecosystem.
Vulnerability Detail
The vulnerability originates from the package's design to include autopublish scripts that automatically generate and publish derivative packages with randomized names. This malicious behavior modifies the package.json file to remove private flags, alters version numbers, and continuously republishes variants, which can lead to pollution of the npm registry and compromise the security of dependent applications. The malicious payload can also affect other packages by creating confusion and potential conflicts in dependency management.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall teagood-cuekin60If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
