Background
rival-poke94 is an npm package that has been associated with the tea.xyz token reward campaign. This package is designed to facilitate certain functionalities within the npm ecosystem but has been compromised to include malicious code. The vulnerability stems from the package's ability to modify its own metadata and republish itself under various names, which can lead to widespread issues in the npm registry.
Vulnerability Detail
The vulnerability in rival-poke94 originates from its malicious payload that alters the package.json file. It removes private flags, changes version numbers, and generates random package names, leading to the creation of numerous derivative packages. This behavior not only inflates developer reputation scores for the tea protocol token rewards but also pollutes the npm registry, making it difficult for developers to trust packages. The malicious scripts (auto.js, autopublish.js, etc.) are designed to automate this process, posing a significant risk to the integrity of the npm ecosystem.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall rival-poke94If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
