Background
The damaged_flea_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, making them a significant risk to developers and users alike.
Vulnerability Detail
The vulnerability in the damaged_flea_z3n package originates from its association with malicious scripts that modify the package.json file.
