Should I take it down?

depends. do you want to deal with a simple patch in 24 hours or do you want to rebuild an entire legacy system from nothing (assuming you don't take proper backups)?

    How dare you (correctly) assume I haven't taken proper backups!

    Jk lol

    I do have a couple backups I made a few months ago. Never tested restoring them, so I don't count them as "real".

    I'm hosting on namecheap servers, using their cpanel and stuff. So I don't have the option of installing my own PHP version, just selecting theirs.

    But apparently they had some mitigations in place before updating, and then they got us updated.
