 "title": "WPS Hide Login <= 1.9.19 - Unauthenticated Login Page Protection Bypass via 'action' Parameter",
 "description": "The WPS Hide Login plugin for WordPress is vulnerable to a login page protection bypass via the 'action' parameter in all versions up to, and including, 1.9.19. This is due to the plugin's password-protected post ('postpass') exemption in its wp_loaded handler. The exemption checked only the query-string 'action' value (and, in versions before 1.7, only that a 'post_password' field was posted), while WordPress's wp-login.php acts on $_REQUEST['action'], where a POSTed value overrides the query string. This makes it possible for unauthenticated attackers to reach the default wp-login.php and its login, lost-password and other actions, which the plugin is configured to hide, and so defeat the hidden login URL (for example, to brute-force credentials).",
