Ruby on Rails app built with Cursor? Let’s review it.
Expert code review for Ruby on Rails apps built with Cursor. We find Cursor-specific bugs, fix Ruby on Rails security issues, and optimize performance. From $19.
Cursor issues we find in Ruby on Rails projects
Problems specific to Cursor's code generation patterns when building Ruby on Rails 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.
Ruby on Rails issues we check for
Common Ruby on Rails problems that affect production readiness.
Mass assignment vulnerabilities
AI-generated Rails controllers that use permit! or don't properly whitelist params, allowing attackers to modify any database column including admin flags and passwords.
Missing authorization checks
Controllers that authenticate users but don't check authorization — a logged-in user can access or modify any other user's data by changing the ID in the URL.
N+1 query problems
ActiveRecord code that loads associated records in loops without includes, eager_load, or preload — causing hundreds of database queries on pages with lists.
Unsafe use of raw SQL
AI tools sometimes generate raw SQL with string interpolation instead of using ActiveRecord's parameterized query methods, enabling SQL injection attacks.
