CVE-2024-1321Network attack vector

Free event bookings via unauthenticated payment updates

Published Mar 13, 2024 · Updated Apr 8, 2026

Payment bypass in Metagauss EventPrime 3.4.2 and earlier allows remote attackers to book paid events without completing payment. The booking payment-status update path accepts an unauthenticated request as proof that an order was paid without verifying the data's authenticity. A site must expose EventPrime's paid-event booking flow; exploitation changes booking integrity and grants event access without payment.
