Why This Matters: Security Beyond Code

For years, Python’s security response was handled by a small, loosely defined group of core developers. While effective, this model wasn’t sustainable. The lack of a public charter made it hard to onboard new members, document responsibilities, or even know who was on the team.

With the approval of PEP 811, the Python Security Response Team (PSRT) now operates under a formal governance structure. This isn’t just paperwork — it’s a critical step toward making Python’s security ecosystem more transparent, accountable, and resilient.

In 2025 alone, the PSRT published 16 vulnerability advisories for CPython and pip — the most in a single year. As the ecosystem grows, so does the attack surface. A formal governance model ensures the team can scale its efforts without burning out its members.

What PEP 811 Actually Changes

Here’s a breakdown of the key improvements introduced by PEP 811:

1. Public Membership List

Previously, PSRT membership was opaque. Now, the team publishes a public list of members, making it clear who is responsible for vulnerability triage and remediation.

2. Defined Roles and Responsibilities

  • Members: triage vulnerabilities, coordinate fixes, and publish advisories.
  • Admins: manage team membership, onboarding, and offboarding.
  • Steering Council Liaison: clarifies the relationship between PSRT and the Python Steering Council.

3. Onboarding & Offboarding Process

A clear, documented process to add or remove members ensures that the team remains sustainable. The first new member under this process is Jacob Coffee, the PSF Infrastructure Engineer, who joined as the first non-Release Manager member since 2023.

4. Coordination with External Projects

PSRT coordinators are encouraged to involve maintainers and experts from affected submodules. This ensures fixes respect existing APIs, maintain long-term stability, and minimize disruption.

5. Recognition for Contributors

New workflows using GitHub Security Advisories will now record reporters, coordinators, and remediation developers. This means private security contributions can be properly credited in CVE and OSV records.

This is a huge step toward making security work as visible and celebrated as code contributions.

How to Get Involved (and Why You Should)

You don’t need to be a core developer to join the PSRT. The team is looking for individuals with security expertise who are known and trusted within the Python community. If you have time to volunteer (or employer support), you could be a strong candidate.

The Nomination Process

  • You need an existing PSRT member to nominate you.
  • Your nomination must receive at least ⅔ positive votes from current members.
  • Once accepted, you’ll have documented responsibilities and are expected to contribute meaningfully to vulnerability remediation.

Important Caveats

  • Membership is not required to receive vulnerability notifications. The PSF is a CVE Numbering Authority and publishes CVE and OSV records publicly.
  • Early notification is not a perk of membership — the process is designed to be transparent.
  • Expect a time commitment — security work is not passive. You’ll be expected to triage, coordinate, and help fix vulnerabilities.

Next Steps

If you’re interested, start by engaging with the Python Security community. Attend Python security sprints, contribute to security-related discussions on discuss.python.org, and build trust within the community. Then, find a current PSRT member who can sponsor your nomination.

Conclusion: A More Secure Python Starts with You

PEP 811 isn’t just a governance document — it’s an invitation. It signals that Python’s security is a shared responsibility, and that the community is ready to welcome new contributors. Whether you’re a security researcher, a DevOps engineer, or a Python enthusiast, there’s a place for you.
