The Eventin – Events Calendar, Event Booking, Ticket & Registration (AI Powered) plugin for WordPress is vulnerable to unauthorized access of data due to a improper capability check on the get_item_permissions_check() function in all versions up to, and including, 4.1.8. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read arbitrary order data including customer PII (name, email, phone) by iterating order IDs.
