Description

The Coming soon and Maintenance mode plugin for WordPress is vulnerable to IP Address Spoofing in all versions up to, and including, 3.7.3 due to the use of user-supplied HTTP headers as a primary method for IP retrieval. This makes it possible for attackers to bypass the coming soon mode page and visit the full site by spoofing an allowed IP.
