Background

The phonoviatts package is a Python library available on the Python Package Index (PyPI) that is likely intended for voice synthesis or related functionalities. However, it has been identified as part of a malicious campaign that enables the execution of remote scripts, posing significant security risks to users and their systems.

Vulnerability Detail

The vulnerability stems from a coordinated campaign involving loader packages that execute code from a specified URL. Although the phonoviatts package does not contain the malicious payload itself, it serves as a vector for downloading and executing potentially harmful scripts. This poses a risk of data theft and system compromise, as the executed scripts can perform unauthorized actions on the user's machine.

How To Fix

This package is malicious. Remove it and rotate any credentials it could have accessed.

pip uninstall phonoviatts

If it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
