Subject: Supply Chain Issues in PyPI
Here is a summary of some security research into the PyPI ecosystem:
https://stiankri.substack.com/p/supply-chain-issues-in-pypi
It includes:
- A PyPI upload Denial of Service vulnerability.
- Challenges with reproducibility in the PyPI ecosystem.
- Distribution Confusion in PyPI: a new way to distribute malicious
packages. Including how it affects Pip and Poetry.
- Manifest Confusion in PyPI: how package managers and security
scanning tools resolve dependencies in different ways.
