Python Advisory DB

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.

Making a pull request

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.

Triage process

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.

Using this data

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"

Longer term, we are working with the PyPI team to build a pipeline to automatically get these vulnerabilities into PyPI. The goal is to have the pip install (and an additional pip audit) command automatically report vulnerabilities out of the box.
