Yeah, for businesses I can see that, but selfhosting, meh. I have just one personal server firewalled and Wireguarded, so the PHP vulnerability wasn’t even publicly exposed. Even so, I have never had any issues with Debian’s unattended security upgrades in the last 5 years.

In enterprise environments with a hundred servers, though, you will want to do something else than I do. :)

But even then, don’t enterprises run a good WAF in front of their public web sites that would have received the patch automatically?
