Apple has released a security update for macOS High Sierra that fixes the (terrifying) root login bug that was first exposed yesterday. The problem appears to have been simple to fix, as Apple had this security patch out in near-record time. Anyone running macOS High Sierra 10.13.1 should make sure they go download and install the update right now.
The root login bug revealed yesterday was the holy grail of security flaws. It allowed anyone to login to a Mac on the root account, simply by entering username "root" and leaving the password field empty. Once someone has root access, there’s basically no limitations to what they can do. Root is a “superuser” account with read and write privileges over the entire system, including other user accounts. That means that anyone with 30 seconds and physical access to your machine can install programs, read and write files and system files, and do basically anything else you can imagine.
