Security Review for your Cursor-built C# app
Expert security review for C# apps built with Cursor. We audit Cursor-generated C# code for security review issues. From $19.
Cursor issues we find in C# projects
Problems specific to Cursor's code generation patterns when building C# 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.
C# security review issues we check for
Security Review-specific C# problems that need attention before production.
Insecure deserialization
Using BinaryFormatter or Newtonsoft with TypeNameHandling.All to deserialize untrusted data, enabling remote code execution.
Missing authorization attributes
ASP.NET controller actions without [Authorize] or policy-based checks, exposing endpoints to unauthenticated users.
Connection string in source code
Database connection strings hardcoded in appsettings.json or source files instead of environment variables or Azure Key Vault.
