Cursor accelerates coding but doesn't audit the code it generates. Here are the production gaps that appear most often in Cursor-built apps.

These aren't hypothetical — they show up in the free audits. See the full production-readiness guide →
Cursor frequently generates Stripe webhook handlers that parse the body but skip `stripe.webhooks.constructEvent`. Without signature verification, anyone can POST fake payment events.
LLM-generated async code often has subtle race conditions — two requests updating the same row simultaneously without transactions or optimistic locking.
Cursor may protect some routes with auth middleware and miss others. A single unprotected route exposing user data is a breach regardless of how many protected ones exist.
Network retries on Stripe calls without idempotency keys can double-charge users. Cursor-generated payment code rarely includes idempotency key handling.
