1. Wordpress username disclosure protection partial bypass
###############################################################################
Preconditions:
* works only for user who is author of the last post
Testing:
Let's try well know Wordpress username disclosure method with activated Wordfence:
http://localhost/wp498/?author=1
Result: "Oops! That page can’t be found."
Now let's try modified query:
http://localhost/wp498/?author[]=
Result: "Author: root"
This method can disclose only one username - from author of the last post
