No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The Timetable and Event Schedule by MotoPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.4.16 via the action_get_event_data due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, to enumerate timeslot IDs and read the full WP_Post object — including post_content, post_excerpt, post_status, and post_author — of draft, pending, and private mp-event posts belonging to other users, along with their associated raw timeslot descriptions.
