Carts, coupons, prices.All exploits, all logic.
Negative-quantity carts, coupon stacking, race conditions on stock: leaks scanners never see. BLSA proves each verdict: rule, path, line.
Retail exploits no SAST tool reads.
Cart logic is its own attack surface. VibeDefend walks it before your agent breaks it.
- Negative-quantity cartsA refactor lets a checkout total go below zero. VibeDefend pins the invariant and rewrites the validator.Caught before checkout
- Coupon stack abuseTwo BFCM codes apply when the rule says one. VibeDefend traces the stack state across the cart lifecycle.Caught before checkout
- Stock race conditionsReservation reads beat the lock under load. VibeDefend restores the order of operations across services.Caught before checkout
BLSA is built in collaboration with the CNRS and the CRIStAL laboratory (Université de Lille). Together we're prototyping a brand-new class of scanner that reasons about your codebase's business logic, the kind of risk no syntactic SAST has ever caught.
