 "title": "EventPrime – Events Calendar, Bookings, Tickets & AI <= 4.3.8.0 - Unauthenticated CSV Injection via Booking and Attendee Data",
 "description": "The EventPrime plugin for WordPress is vulnerable to CSV Injection via booking and attendee data in all versions up to, and including, 4.3.8.0, due to insufficient neutralization of spreadsheet formula characters in the values it writes to the bookings and attendees CSV exports. This makes it possible for unauthenticated attackers who submit a booking to embed formulas in attendee details. The formulas run on the computer of a site administrator who exports the data and opens the file in a spreadsheet application.",
