The Python Package Index (PyPI) now rejects new files being uploaded to releases that are older than 14 days. This restriction was put in place to prevent old and long-stable releases from being poisoned in case publishing tokens or workflows of PyPI projects were compromised. As far as we are aware this has not yet been abused, but there is no technical reason beyond that attackers weren't aware it was possible.
Over the next few months, we will be rolling out changes to the PyPI user interface, improving how we surface security signals and updating the pages where users view package details.
Updates will be staged to TestPyPI and deployed to production in phases. This approach allows our team to thoroughly test the UI with production-like data, while providing the community with an opportunity to share feedback.
The first phase of changes is now staged on TestPyPI and ready for users to review!
In 2023 PyPI completed its first security audit, and I am proud to announce that we have now completed our second external security audit.
This work was funded by the Sovereign Tech Agency, a supporter of Open Source security-related improvements, partnering with Trail of Bits to perform the audit. Thanks to ongoing support from Alpha-Omega, my role at the PSF enabled me to focus on rapid remediation of the findings.
This time around, there's no three-part series, as the scope was narrower, focused only on PyPI's codebase and behaviors. Read on for a summary of issues identified, their resolutions, and more details about the audit process.
This post will drill deeper into two recent supply chain exploits, targeting users of popular PyPI packages - litellm & telnyx.
We also provide Python developers and maintainers with guidance on what they can do to prepare
and protect themselves from future incidents.
Hello there! I am Maria, the inaugural PyPI Support Specialist. I go by "Thespi-Brain" on GitHub. I wanted to provide a dispatch of how this past year (and a half!) has been regarding my role and PyPI. PyPI has now reached over a million users and has over 700,000 projects. It is, without a doubt, a critical part of the Python ecosystem. As the inaugural PyPI Support Specialist, there were numerous challenges that needed to be tackled regarding PyPI support, such as the ever growing backlog of account recovery and PEP 541 issues.
