 "title": "Event Tickets and Registration <= 5.31.0 - Unauthenticated Missing Authorization to Attendee Check-in Status Disclosure via QR REST Endpoint",
 "description": "The Event Tickets and Registration plugin for WordPress is vulnerable to unauthorized access of data via the QR REST endpoint (/wp-json/tribe/tickets/v1/qr/<id>) in versions 5.7.0 up to, and including, 5.31.0, due to a missing manage-access check in the endpoint's GET handler, which is registered with a permission callback that allows everyone. This makes it possible for unauthenticated attackers to find out whether any attendee, chosen by ID, has been checked in.",
