Background

The inagi-vumafe-nafus package is part of the npm ecosystem, often utilized in various JavaScript applications. It is associated with the tea.xyz token reward campaign, which has been known to flood the npm registry with numerous packages. This package, like others in the campaign, is designed to manipulate developer reputation scores by automatically generating and publishing derivative packages with randomized names.

Vulnerability Detail

The vulnerability in the inagi-vumafe-nafus package 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 poses a risk to developers who may unknowingly use these compromised packages, potentially leading to security breaches and loss of trust in the npm ecosystem.

How To Fix

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

npm uninstall inagi-vumafe-nafus
