Apple quick to release security update to fix the problem
 https://support.apple.com/en-us/HT208315
“Everyone running macOS 10.13.1 High Sierra should install this security update 
via Software Update immediately. It does not require a restart. I know that we 
usually recommend caution when it comes to installing updates, but this 
vulnerability is so severe that the fix is more important than any trouble it 
could conceivably cause. That said, make sure you have a backup first!

In a statement to Daring Fireball's John Gruber, Apple said:

Security is a top priority for every Apple product, and regrettably we stumbled 
with this release of macOS. When our security engineers became aware of the 
issue Tuesday afternoon, we immediately began working on an update that closes 
the security hole. This morning, as of 8:00 a.m., the update is available for 
download, and starting later today it will be automatically installed on all 
systems running the latest version (10.13.1) of macOS High Sierra. We greatly 
regret this error and we apologize to all Mac users, both for releasing with 
this vulnerability and for the concern it has caused. Our customers deserve 
better. We are auditing our development processes to help prevent this from 
happening again.

Although the community identified the primary attack vectors yesterday, it’s 
possible that there are others that are not blocked by changing the root 
password or disabling remote access. We have to assume that black hat hackers 
are already probing every possible area where this bug could provide access.

Apple notes that after installation, the build number of macOS will be 17B1002. 
To verify that number, choose  > About This Mac and click the Version 10.13.1 
line.”
