What it is

From the CVE record

The EventPrime – Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘ep_booking_attendee_fields’ fields in all versions up to, and including, 4.0.4.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses the transaction log for a booking.
