Background
The package @angularr/cli is a malicious npm package that impersonates the official Angular CLI. It is designed to mislead users by copying the description, keywords, and other metadata from the legitimate @angular/cli package. This package is particularly dangerous as it executes arbitrary code during installation, posing a significant risk to users' systems.
Vulnerability Detail
The vulnerability stems from the malicious code embedded in the @angularr/cli package, which includes a preinstall lifecycle hook that fetches and executes a remote JavaScript file from an untrusted source. This file is hosted on gitflic.ru and is executed directly by the Node.js process during the installation of the package. The lack of integrity checks and the unpinned nature of the script allow for arbitrary code execution, potentially compromising the user's system and data.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall @angularr/cliIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.

Conclusion
The @angularr/cli package poses a significant security threat due to its malicious code execution capabilities. Users must take immediate action to remove this package and replace it with the official Angular CLI to safeguard their systems. Regular monitoring for vulnerabilities using tools like Vulert is recommended to maintain security.
