auditing-python-dependencies
Audit a Python project's installed dependencies for known CVEs by wrapping pip-audit (PyPA's official vulnerability auditor) and emitting findings in the canonical penetration-tester schema. Detects vulnerable direct AND transitive packages, normalizes pip-audit's severity output via OSV severity bands, falls back to pip list --outdated when pip-audit isn't installed, and supports requirements.txt, pyproject.toml (PEP 621), Pipfile.lock, and poetry.lock as input sources. Use when: pre-merge gate on a Python project, post-incident sweep after a PyPI compromise (e.g. ctx, request-toolbelt typosquats, ultralytics 8.3.42 compromise), SOC2 evidence collection, or inheriting an unfamiliar Python codebase. Threshold: any HIGH or CRITICAL CVE in the resolved dependency tree. MODERATE / LOW reported informationally. Trigger with: "audit python deps", "pip vulnerability scan", "check pypi packages for CVEs", "pip-audit run".

# Auditing Python Dependencies
## Overview
PyPI hosts north of 500,000 packages, with several thousand new
releases every day. The package-install model is identical to npm in
the relevant ways: a `pip install` resolves a transitive graph,
runs each package's `setup.py` (which executes arbitrary Python at
install time), and writes the result to your site-packages. The CVE
attack surface is therefore the same shape: known vulnerabilities,
maintainer-account takeovers, typosquats, and protestware.
The PyPA-blessed auditor is `pip-audit`. It queries the Open Source
Vulnerabilities (OSV) database (which mirrors PyPA's advisory feed
