Background

sinta-lapis25-miaww is an npm package that is part of the tea.xyz token reward campaign. This package is designed to facilitate the distribution of token rewards through various npm packages. However, it has been identified as containing malicious code that compromises its integrity and the security of the npm ecosystem.

Vulnerability Detail

The vulnerability in sinta-lapis25-miaww originates from its inclusion in a campaign that floods the npm registry with malicious packages. These packages contain scripts that automatically modify their own package.json files to remove private flags, alter version numbers, and generate random package names. This behavior leads to the pollution of the npm registry and can inflate developer reputation scores fraudulently. The malicious payload poses significant risks, including the potential for further exploitation and the degradation of trust in the npm ecosystem.

How To Fix

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

npm uninstall sinta-lapis25-miaww

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