CVE-2026-12956Network attack vector

Unauthenticated ticket inventory exhaustion via forged orders

Published Sep 9, 2026 · Updated Sep 9, 2026

Missing authorization in Arraytics Eventin 4.1.22 and earlier allows remote attackers to exhaust ticket inventory through forged orders. The orders REST handler accepts a visitor-exposed nonce and passes an unvalidated status into order creation, allowing completed orders to persist. No account is required; the forged records inflate sold-ticket counts and prevent legitimate ticket availability without exposing customer data.
