Direct answer
Assume a vibe app will leak a key or mishandle a webhook until proven otherwise. Keep secrets server-side, verify webhooks, idempotent payment processing, and rate-limit sensitive endpoints.
Secrets
No service keys in frontend bundles or public repos. Rotate anything that ever leaked.
Stripe
Webhook signatures, raw body verification, idempotency keys, reconcile under/over pay.
Admin and promo
Rate limits, lockouts, audit logs - AI scaffolds often skip them.
Bot abuse
CAPTCHA or equivalent on costly public endpoints.

FAQ
