Background

The riyanto-poke90 package is part of the npm ecosystem, which is widely used for JavaScript package management. This package, like many others, is intended to facilitate the development of applications by providing reusable code. However, it has been identified as part of a malicious campaign that aims to exploit the npm registry by flooding it with derivative packages, thereby inflating developer reputation scores for token rewards.

Vulnerability Detail

The vulnerability in riyanto-poke90 stems from its association with a malicious campaign that modifies the package.json file to remove private flags, alters version numbers, and generates random package names. This behavior is designed to pollute the npm registry, making it difficult for developers to identify legitimate packages. The malicious code can lead to security risks, including the potential for unauthorized access to sensitive information or the introduction of further vulnerabilities into dependent applications.

How To Fix

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

npm uninstall riyanto-poke90
