Background

The fond_caribou_0xrequest package is part of the npm ecosystem, often used in JavaScript applications. It is associated with the tea.xyz token reward campaign, which has been known to flood the npm registry with packages that manipulate developer reputation scores. This package, like others in the campaign, is designed to automatically generate and publish derivative packages, potentially leading to significant pollution of the npm registry.

Vulnerability Detail

The vulnerability in the fond_caribou_0xrequest package arises from malicious code that modifies the package.json file. This code removes private flags, alters version numbers, and generates random package names, primarily themed around Indonesian culture. The malicious payload continuously republishes these variants, which can lead to a polluted npm registry and compromise the integrity of the ecosystem. The origin of this vulnerability is linked to the tea.xyz token reward campaign, which incentivizes developers to inflate their reputation scores through such practices.

How To Fix

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

npm uninstall fond_caribou_0xrequest

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