Background
The madan-poke25 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 and deployment of applications. However, it has been identified as part of a malicious campaign that aims to manipulate the npm registry by generating and publishing numerous derivative packages with altered metadata. This behavior not only undermines the integrity of the npm ecosystem but also poses significant risks to developers and users relying on these packages.
Vulnerability Detail
