 "title": "Ultimate Dashboard – Custom WordPress Dashboard <= 3.8.18 - Unauthenticated Protection Mechanism Bypass via Password-Protected Post Requests",
 "description": "The Ultimate Dashboard plugin for WordPress is vulnerable to a bypass of its custom login URL protection via password-protected post (postpass) requests in all versions up to, and including, 3.8.18, due to the protect_wp_login() function skipping its protection whenever the query string has action=postpass and a post_password parameter is present, while wp-login.php takes the action from $_REQUEST, where a POST 'action' field overrides the query string. This makes it possible for unauthenticated attackers to use the default wp-login.php for other actions, such as logging in, even though the site owner enabled a custom login URL to hide it. Exploitation requires the custom login URL feature to be enabled.",
