Background
The package 'testingpkgja' is a Python package available on PyPI, designed for testing purposes. It is intended to assist developers in conducting various tests and experiments. However, it has been identified to contain malicious code that executes an external executable during installation, posing a significant security risk to users who install it.
Vulnerability Detail
The vulnerability stems from the package overriding the install command in its setup.py file, which allows it to execute arbitrary code during the installation process.
