Shopware’s Voucher Chaos: Unfixed Bug Lets Shoppers Race to Unlimited Discounts!
A race condition in Shopware voucher submission (CVE-2025-7954) lets attackers bypass usage limits. The vendor calls it a “bug” and merchants can cancel orders, but until a patch arrives, using limited vouchers is like playing roulette with your profits.

Hot Take:
Well, it looks like Shopware’s voucher system is racing faster than a caffeinated hamster on a wheel! With no patch in sight, merchants might as well be handing out free candy in a kindergarten.
