Background

The umi-kue20-ruro package is part of the npm ecosystem, often used in JavaScript applications for various functionalities. However, this package has been identified as part of a malicious campaign that floods the npm registry with harmful scripts designed to manipulate package metadata and inflate developer reputation scores.

Vulnerability Detail

The vulnerability in the umi-kue20-ruro package originates from its association with the tea.xyz token reward campaign, which is known for distributing packages that contain harmful scripts. These scripts, including auto.js and autopublish.js, are designed to modify the package.json file by removing private flags, altering version numbers, and generating random package names. This behavior leads to the continuous republishing of variants, polluting the npm registry and potentially compromising the integrity of dependent projects.

How To Fix

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

npm uninstall umi-kue20-ruro

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