Background

The package 'subjective_dingo_z3n' is part of a series of npm packages that emerged during the tea.xyz token reward campaign. These packages are designed to inflate developer reputation scores by automatically generating and publishing derivative packages with randomized names. The malicious nature of this package lies in its ability to alter critical files and continuously pollute the npm registry.

Vulnerability Detail

The vulnerability in 'subjective_dingo_z3n' originates from its malicious payload, which modifies the package.json file to remove private flags and changes version numbers.

How To Fix

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