Background

The package 'intan-76' is part of the npm ecosystem, which is widely used for JavaScript package management. It is associated with the tea.xyz token reward campaign, which has been known to flood the npm registry with malicious packages. These packages are designed to inflate developer reputation scores through automated scripts that generate and publish derivative packages with random names.

Vulnerability Detail

The vulnerability in 'intan-76' originates from its malicious payload, which modifies the package.json file to remove private flags, alters version numbers, and generates random package names. This behavior leads to the continuous republishing of variants, effectively polluting the npm registry and potentially compromising the integrity of other packages. The malicious code can also impact developers by falsely inflating reputation scores and introducing security risks into their projects.

How To Fix

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

npm uninstall intan-76

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