Finding and Plugging a CVE

Braidon Whatley & Julian Doherty

Braidon Whatley and Julian Doherty walk through how Braidon discovered and reported CVE-2026-54892, a high-severity denial-of-service vulnerability in Plug. A look at how a subtle bug in a widely-used library turns into a serious security problem, and how responsible disclosure works in the BEAM ecosystem.

Up next · 7:00

It's time! PostgreSQL 19 for temporal data

Mike Buhot · Alembic

Postgres 19 beta is out, and ships with some amazing new features for working with temporal data models. In this talk, I'll cover how to design a temporal schema, giving you time travel super powers to query your database as of any time in the past or future! We'll look at practical tools for Elixir developers, accessing the new features from Ecto, Ash, and Gleam.

That's a wrap

Thank you

Thanks for coming. Stick around for a chat, and we're always after speakers, first-timers included.
