RegistrationMagic < 5.2.5.1 - IP Spoofing

Description The RegistrationMagic – Custom Registration Forms, User Registration, Payment, and User Login plugin for WordPress is vulnerable to IP Address Spoofing in all versions up to, and including, 5.2.5.0 due to use of user-supplied HTTP headers as a primary method for IP retrieval. This makes it possible for unauthenticated attackers to submit more form entries than the form submission limit allows.
