Background
The 'embarrassed_wolf_z3n' package is part of the npm ecosystem and appears to be associated with a token reward campaign by tea.xyz. This package is designed to facilitate the automatic generation and publication of derivative packages, often with randomized names, to inflate developer reputation scores for token rewards. Its functionality is compromised due to the presence of malicious scripts that manipulate package metadata.
Vulnerability Detail
The vulnerability originates from the package's design, which includes autopublish scripts that modify the package.json file. These scripts remove private flags, alter version numbers, and generate random package names, leading to the continuous republishing of variants that pollute the npm registry. This not only affects the integrity of the npm ecosystem but also poses risks to developers who may unknowingly use these compromised packages.
