Advisory
Source description from Wordfence Intelligence, credited to Kévin Mosbahi (Mika).
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.
