Background

cometdreamer is an npm package that is part of the tea.xyz token reward campaign. This package is designed to facilitate token rewards through various automated scripts. However, it has been identified as containing malicious code that compromises the integrity of the npm registry by generating and publishing derivative packages with altered metadata.

Vulnerability Detail

The vulnerability in cometdreamer originates from its involvement in a malicious campaign that floods the npm registry with derivative packages. These packages contain scripts that modify the package.json file, removing private flags, changing version numbers, and generating random package names. This behavior not only inflates developer reputation scores but also pollutes the npm registry, making it difficult for developers to find legitimate packages. The malicious payload can lead to security risks, including unauthorized access and potential exploitation of affected systems.

How To Fix

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

npm uninstall cometdreamer

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