Background
The favourite_dormouse-appteadev package is part of the npm ecosystem, typically used for various development purposes. However, it has been identified as part of a malicious campaign aimed at manipulating the npm registry. This package is associated with the tea.xyz token reward initiative, which has led to the creation of numerous derivative packages that can compromise the integrity of the npm ecosystem.
Vulnerability Detail
The vulnerability originates from the package's malicious code, which modifies the package.json file to remove private flags, alters version numbers, and generates random package names.
