Stripe app built with Cursor? Let’s review it.
Expert code review for Stripe apps built with Cursor. We find Cursor-specific bugs, fix Stripe security issues, and optimize performance. From $19.
Cursor issues we find in Stripe projects
Problems specific to Cursor's code generation patterns when building Stripe apps.
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
Race conditions in state management
Multiple rapid state updates or concurrent API calls cause stale data, UI flickers, and inconsistent behavior — especially in forms and real-time features.
Stripe issues we check for
Common Stripe problems that affect production readiness.
Missing webhook signature verification
Webhook endpoints that accept any payload without verifying the Stripe signature, allowing attackers to fake payment events.
Client-side price manipulation
Prices passed from client to server instead of using Stripe Price IDs, allowing users to pay any amount they choose.
No idempotency handling
Duplicate webhook deliveries processed multiple times, causing double charges or duplicate order creation.
Missing subscription lifecycle handling
No handling for failed payments, subscription cancellations, downgrades, or payment method updates.
