This is community owned repository of advisories for packages published on https://pypi.org.

Advisories live in the vulns directory and use a YAML encoding of a simple format.

Existing entries can be edited by simply creating a pull request.

To introduce a new entry, create a pull request with a new file that has a name matching PYSEC-0000-<anything>.yaml. This will be later picked up by automation to allocate a proper ID once merged.

Much of the existing set of vulnerabilities are collected from the NVD CVE feed.

We use this tool, which performs a lot of heuristics to match CVEs with exact Python packages and versions (which is a difficult problem!) and a small amount of human triage to generate the .yaml entries here.

This data is exposed by pip-audit, which provides a CLI for resolving Python dependencies in an environment or project and identifying known vulnerabilities:

python -m pip install pip-audit
python -m pip-audit -r requirements.txt

You can also use pypa/gh-action-pip-audit on GitHub Actions:

jobs:
  pip-audit:
    steps:
      - uses: pypa/gh-action-pip-audit@v1.0.8
        with:
          inputs: requirements.txt

Vulnerabilities are integrated into the Open Source Vulnerabilities project, which provides an API to query for vulnerabilities like so:

$ curl -X POST -d \
          '{"version": "2.4.1", "package": {"name": "jinja2", "ecosystem": "PyPI"}}' \
          "https://api.osv.dev/v1/query"

This data has also been integrated into the PyPI JSON API.

Everyone interacting with this project is expected to follow the PSF Code of Conduct.
