Background

teaa-reborn31 is an npm package that is part of the tea.xyz token reward campaign. This package is designed to facilitate the distribution of token rewards through various scripts. However, it has been identified as malicious due to its capability to manipulate package metadata and flood the npm registry with derivative packages, which can mislead developers and inflate reputation scores.

Vulnerability Detail

The vulnerability in teaa-reborn31 originates from its malicious code that modifies the package.json file. This code removes private flags, alters version numbers, and generates random package names, which allows it to continuously republish variants to the npm registry. The ramifications include pollution of the npm registry, potential security risks for developers using these packages, and a compromised reputation system within the npm ecosystem.

How To Fix

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

npm uninstall teaa-reborn31

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