brew-pip-audit: Bulk auditing Python dependencies in Homebrew with osv-scanner

Homebrew is a popular package manager for macOS. Many of the projects it packages are written in Python. In order to ensure reproducible builds, Homebrew precisely pins the version of each Python package a Homebrew formula depends on.

osv-scanner is a tool for checking a project's dependencies against vulnerability databases in order to determine if there are any known vulnerabilities.

This project takes all of the Python packages depended on by Homebrew formulas and runs them through osv-scanner. It then takes those audit results and uses them to submit patches to Homebrew.

This project previously used pip-audit, instead of osv-scanner, hence the name.

The repo

The following things can be found in this repository:

• formula2requirements.rb: Extracts the Python dependencies from Homebrew and writes them out in the requirements.txt format.
• pip-audit-bulk: Runs osv-scanner over a directory of requirements.txt files.
• generate-prs.rb: Automatically generates PRs against Homebrew/homebrew-core for formulae with vulnerable dependencies.

See the generated GitHub Pages site for more information, including generated dependency sets and audits.

Contributing

This repository is automated, but the automation isn't perfect. You can help out by:

• Looking at the incoming PRs against Homebrew/homebrew-core, and helping debug ones that fail.
• Improving the performance of our automation (it's currently very slow).
• Looking at the action logs for the PR automation, and helping debug/fix formulae and dependencies that can't be auto-updated.
