CVE-2026-101273

Giftcard enumeration

Published Oct 28, 2026 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed
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.
