 Hey look at what i got, i managed to replicate!

 In the proxy i put
  X-Forwarded-For: 2001:db8::1:2:3:4:5:6:7
 in the get request for the wp-admin
  GET http://localhost:8889/wp-admin/ HTTP/1.1
 When the admin panel loads, it shows this:
  Fatal error: Uncaught TypeError: Unsupported operand types: bool & string
 in /var/www/src/wp-includes/functions.php:8265 Stack trace: #0
 /var/www/src/wp-admin/includes/class-wp-community-events.php(273):

 So yeah we crashed the wp-admin panel by having a broken ip.

 This could be something, i will proceed to try to crash this with an real
 ipv6 address, or maybe it is just nothing...
