WordPress Improper Input Validation Vulnerability - CVE-2020-35539

A flaw was found in Wordpress 5.1. quotX-Forwarded-Forquot is a HTTP header used to carry the client39s original IP address. However because these headers may very well be added by the client to the requests if the systems/devices use IP addresses which decelerate at X-Forwarded-For header instead of original IP various issues may be faced. If the data originating from these fields is trusted by the application developers and processed any authorization checks originating IP address logging could be manipulated.
