How to act on this list

1. Start with anything marked exploited or patch now.
2. Check what you run: see how to check a version and patch it on Linux, Windows, pip and npm.
3. Prefer the vendor or distro fix. If none exists, read when to downgrade and when to mitigate.
4. Verify afterwards. Distros often fix a flaw without changing the upstream version, here is how to confirm.
