The Erlang Ecosystem Foundation CNA now publishes vulnerability data directly to OSV.dev. No more relying solely on CVE→OSV conversion.

This update means faster, cleaner, and higher-quality security data for the BEAM ecosystem — including Erlang, Elixir, Gleam, and Hex.pm.

We’ve also expanded our scope to include:
@nervesproject
OpenRiak

The EEF CNA (http://cna.erlef.org/) will handle vulnerability disclosures for these projects, going forward and strengthening coordinated security across the BEAM ecosystem.

All part of our ongoing ÆGIS Initiative: https://security.erlef.org/aegis

What if the BEAM got hit by a worm? 🪱

We’ve been lucky so far — but luck runs out.
The Ægis Initiative is how we defend our ecosystem.

🔐 Security and the BEAM Ecosystem

In this insightful session organized by @erlangsolutions, @maennchen — CISO at our Foundation —shares how the BEAM community is stepping up its open source security efforts, including becoming an official CVE Numbering Authority (CNA).

What you’ll learn:
✔️Why the EEF became a CNA and how it helps the BEAM community
✔️Common security risks developers overlook and how to avoid them
✔️How better vulnerability tracking and tooling can reduce future problems
✔️Why early, simple steps toward security save time and effort later

🔐 Big news from the #Gleam community!

The EEF Security Working Group helped @gleamlang include Build SBoMs and SLSA build provenance for all release artifacts and Docker images.

This means greater visibility into dependencies and stronger software supply chain security. 💪

Starting with version v1.10.0, every Gleam release will feature these important security details.

📢 Why did we launch the Supply Chain Security & Compliance Initiative (ÆGIS)?

Because we believe a safer BEAM ecosystem benefits us all.
Here’s what we’re aiming for:

🔒 Elevate ecosystem-wide security
✅ Streamline compliance readiness
🤝 Foster trust and transparency
🌍 Democratize access to advanced security
🚀 Enable secure publishing workflows

@seldaek Thanks 😊 I know about the possibility of restricting to 64bit. I was just interested how many users of my libary would be excluded by adding it. Sadly I can’t find any statistics about it anywhere.

@seldaek If I remember correctly, you published yearly PHP version statistics of composer users. Do you know the share of 32-bit vs 64-bit users as well?

I'm trying to decide for a package that needs 64-bit integers and uses a Polyfill for it if we can retire 32-bit support.
