Unauthenticated Cross Site Scripting (XSS) in Profile Builder Pro <= 3.15.0 versions.

The Profile Builder Pro plugin for WordPress is vulnerable to PHP Object Injection in all versions up to and including 3.14.5. This is due to the use of PHP's maybeunserialize() function on the attacker-controlled 'args' POST parameter within the wppbrequestuserspinsactioncallback() AJAX handler, which lacked any nonce verification, type checking, or input validation before deserialization. Because the handler was registered with both wpajax and wpajaxnopriv hooks, it was reachable by completely unauthenticated users. This makes it possible for unauthenticated attackers to inject arbitrary PHP objects into application memory.
