The weak point is not Chick-fil-A’s backend. It is customer password reuse, which lets a breach on some other site become a working login here without any direct compromise of Chick-fil-A itself.
Chick-fil-A said a June 17–19 credential stuffing wave led to more than 13,000 customer account takeovers on its website and mobile app. Attackers used email-and-password pairs from other breaches, and successful logins gave them real customer access that can look like normal activity.
For consumer services with password-based accounts, the risk is account-layer fraud, not infrastructure damage. Patched systems do not matter if the stolen credentials still open live customer sessions elsewhere.
