Description
The Event Tickets and Registration plugin for WordPress is vulnerable to Sensitive Information Exposure via the attendees archive REST endpoint (/wp-json/tribe/tickets/v1/attendees) in all versions up to, and including, 5.31.0, due to the endpoint applying the email search, order ID, order status, check-in, price and attendee information filters, and slug ordering, to requests that do not have manage access. This makes it possible for unauthenticated attackers to use these filters as a yes/no oracle against the publicly listed attendees, inferring attendee email addresses, order IDs, prices paid and check-in state that the public response does not show.
