Background

The package tealove-coki49 is part of a broader campaign associated with the tea.xyz token reward system. This npm package is designed to manipulate the npm registry by generating and publishing derivative packages with randomized names. Its primary function is to inflate developer reputation scores for token rewards, but it poses significant risks due to its malicious payload.

Vulnerability Detail

The vulnerability in tealove-coki49 stems from its malicious code that modifies the package.json file. It removes private flags, alters version numbers, and generates random package names, leading to the continuous republishing of these variants. This behavior not only pollutes the npm registry but also compromises the integrity of the packages within it. The origin of this vulnerability is linked to the tea.xyz token reward campaign, which exploits npm's publishing mechanisms.

How To Fix

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

npm uninstall tealove-coki49

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