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