Background

The delicate_snake_z3n package is part of the npm ecosystem, which is widely used for JavaScript package management. This package is associated with the tea.xyz token reward campaign, which has been known to flood the npm registry with malicious packages. These packages often contain scripts designed to manipulate package metadata and inflate developer reputation scores, posing a significant risk to developers and users alike.

Vulnerability Detail

The vulnerability in the delicate_snake_z3n package originates from its association with a malicious campaign that utilizes autopublish scripts to generate and publish derivative packages with randomized names. This manipulation modifies the package.json file by removing private flags, altering version numbers, and continuously republishing variants, which can lead to pollution of the npm registry and compromise the integrity of the software supply chain.

How To Fix

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

npm uninstall delicate_snake_z3n

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