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.\n\n## Affected\n\n- `pretix < 2026.6.4`\n- `pretix >= 2026.7.0 < 2026.7.3`\n- `pretix >= 2026.8.0 < 2026.8.1`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":29,"depthScoreParts":{"impact":29.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
