Joomla com_booking component 2.4.9 contains an information disclosure vulnerability that allows unauthenticated attackers to enumerate user accounts by exploiting the getUserData function in the customer controller. Attackers can send GET requests to index.php with option=com_booking, controller=customer, task=getUserData, and an id parameter to retrieve user names, usernames, and email addresses through brute force enumeration.
