Hi.Events before 1.11.0 contains a missing server-side visibility enforcement vulnerability that allows unauthenticated attackers to purchase hidden tickets by referencing hidden product and price IDs in order creation requests without authorization checks. Attackers can enumerate sequential hidden ticket IDs from visible ones and submit order creation requests referencing those IDs to purchase VIP, invite-only, or discounted tickets intentionally withheld from public sale.
