Adding UploadThing to your Cursor app? Let us review it.
Expert review for UploadThing integrations built with Cursor. We fix Cursor-generated UploadThing code for security, error handling & production readiness. From $19.
Common Cursor issues affecting integrations
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.
UploadThing issues we find in Cursor apps
File router middleware not checking authentication
AI-generated file routers skip auth checks in the middleware function, allowing unauthenticated users to upload files to your storage.
File size and type limits too permissive
Generated code uses generous defaults or omits file type restrictions, allowing users to upload any file type up to the maximum size limit.
onUploadComplete callback not persisting file metadata
AI tools log the upload URL in the callback but don't save it to the database, meaning the file exists in storage but your app has no reference to it.
