Modern Events Calendar Lite < 7.37.0 - Subscriber+ Sensitive Data Disclosure via mec_event_bookings and mec_attendees AJAX Actions

The Modern Events Calendar Lite WordPress plugin before 7.37.0 does not perform capability, nonce, or ownership checks before returning event booking and attendee data, allowing any authenticated user, including Subscribers, to disclose the names, email addresses, transaction IDs and payment amounts of every booking on the site.
