Background

The seblakkuah11 package is part of the npm ecosystem and is associated with the tea.xyz token reward campaign. This package is designed to facilitate the automatic generation and publication of derivative packages, which can inflate developer reputation scores in exchange for token rewards. However, it has been identified as containing malicious code that alters its own package.json file and republishes variants to pollute the npm registry.

Vulnerability Detail

The vulnerability in the seblakkuah11 package stems from its malicious payload that modifies the package.json file to remove private flags, changes version numbers, and generates random package names. This behavior is intended to create numerous derivative packages that can mislead developers and compromise the integrity of the npm registry. The origin of this vulnerability is linked to a broader campaign that exploits npm's publishing capabilities to manipulate developer reputation scores.

How To Fix

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

npm uninstall seblakkuah11

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