Background
The notr-ucl-vibni package is part of the npm ecosystem, which is widely used for managing JavaScript packages. 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 exploits npm's publishing mechanisms, leading to significant security risks for developers and their projects.
Vulnerability Detail
The vulnerability in the notr-ucl-vibni package stems from its involvement in the tea.xyz token reward campaign, which floods the npm registry with malicious packages.

The malicious payload alters the package.json file by removing private flags, changing version numbers, and continuously republishing variants. This behavior can lead to compromised developer reputation scores and potential security breaches in applications relying on these packages.
