SiteGuard WP Plugin provides a functionality to customize the path to the login page wp-login.php and implements a measure to avoid redirection from other URLs. However, SiteGuard WP Plugin versions prior to 1.7.7 missed to implement a measure to avoid redirection from wp-register.php. As a result, the customized path to the login page may be exposed.
