Adding AWS S3 to your Cursor app? Let us review it.
Expert review for AWS S3 integrations built with Cursor. We fix Cursor-generated AWS S3 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.
AWS S3 issues we find in Cursor apps
S3 bucket configured with public read/write access
AI-generated code sets the bucket ACL to public-read-write or uses a bucket policy that grants s3:* to everyone, exposing all files and allowing arbitrary uploads.
AWS credentials hardcoded or in client-side code
Generated code includes AWS access key ID and secret access key directly in source files or client-side environment variables instead of using IAM roles or presigned URLs.
File uploads sent through the server instead of presigned URLs
AI tools route all file uploads through your server, creating a bandwidth bottleneck and unnecessary cost, instead of using S3 presigned URLs for direct browser-to-S3 uploads.

Common issues in Cursor-generated AWS S3 code include: s3 bucket configured with public read/write access, aws credentials hardcoded or in client-side code, file uploads sent through the server instead of presigned urls. We fix all of these in our code review.
How much does it cost to fix my AWS S3 integration?
Start with our code audit ($19) to get a complete list of AWS S3 issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What AWS S3 best practices does Cursor typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for AWS S3. Our review checks all of these and provides specific fixes.
