CVE-2024-9865: Metagauss Eventprime

Medium severity, CVSS 6.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Metagauss Eventprime: before 4.0.4.8 (fixed in 4.0.4.8)
