Summary
This vulnerability affects the API of an online ticketing and event management platform, which lets organizers sell gift cards to customers. An attacker could exploit the missing ownership check to access gift cards belonging to other organizers, reveal their secret codes, and increase their balance through refunds.

Read the original description
Some of our API endpoints allowed to create order payments referencing a gift card by using the auto-incremented internal ID. This ID was not checked and allowed creating payments that reference gift cards from different organizers and thereby obtaining their secret. The gift card is not charged in this case, but by then triggering a refund on the payment, one can increase the value of the gift card.
