CVE-2026-11764 PUBLISHED

Data exposed without proper permission

Assigner: rami.io
Reserved: 09.06.2026 Published: 09.06.2026 Updated: 09.06.2026

When creating an export of all reusable media, the secrets of connected gift cards were included in the export even if the user creating the export does not have permission to view gift cards. This is inconsistent with the UI and API where only the first letters of the gift card secret are shown. Therefore, it allows circumventing a permission boundary.
