Comment:

 @ArtZ91 I need to check, but judging from your environment, my intuition
 says that the problem is with Apache2, it’s not sanitizing the Host
 header.

 I'm going to see if I can setup an Apache host a try again (wordpress-
 develop env by default uses nginx reverse proxy with FPM-PHP hosts for
 WP). Still if this is the problem, host existance should be checked before
 using it in the informed variable, hence, there is a potential issue to be
 sorted, just we need some reproduction steps to consistently reproduce
 this issue until it gets sorted.
