          "value": "The Security Hardener plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 2.4.4. The vulnerability exists because the plugin\u0027s user-enumeration protection, which is enabled by default, hooks the rest_endpoints filter via secure_user_endpoints() and overwrites every registered handler\u0027s permission_callback on both the /wp/v2/users and /wp/v2/users/(?P\u003cid\u003e[\\d]+) routes \u2014 including POST, PUT, PATCH, and DELETE handlers \u2014 with a bare closure that returns only is_user_logged_in(), completely stripping WordPress Core\u0027s original capability checks such as create_users, promote_user, edit_users, and delete_users that WP_REST_Users_Controller normally enforces. This makes it possible for authenticated attackers with Subscriber-level access and above to create new Administrator accounts by sending POST request to /wp/v2/users with administrator role, or to reset an existing Administrator\u0027s password by issuing a PUT/POST request to /wp/v2/users/\u003cid\u003e. Because the block_user_enum option defaults to enabled, no special plugin configuration is required \u2014 the overwrite is active on every request as soon as the plugin is installed."
