| Description | A race condition vulnerability was discovered in the gift voucher redemption process of grandnode/grandnode2. The flaw allows multiple distinct users or guests to redeem the same voucher concurrently via /checkout/ConfirmOrder/ endpoint. This can enable attackers with guest sessions or multiple accounts to redeem a single voucher multiple times across different guest sessions/accounts, potentially resulting in unauthorized financial gain. The vendor has been contacted privately without any responses. |
