Security Vulnerabilities in AI-Generated Code

AI coding tools often generate code with exposed API keys, missing input validation, broken authentication, and insecure data handling. These vulnerabilities can lead to data breaches, unauthorized access, and compliance failures.

3 tools can help2 verified agencies

Common Symptoms

  • API keys or secrets visible in client-side code
  • No input validation on forms or API endpoints
  • Authentication bypasses or weak session handling
  • Missing CORS, CSP, or other security headers
  • SQL injection or XSS vulnerabilities in generated code
  • Sensitive data exposed in URL parameters or logs

Try These Fixes First

Before hiring an agency, try these steps yourself. Many common issues can be resolved with the right approach.

1

Run a security scanner (e.g., npm audit, Snyk) on your codebase

2

Move all secrets to environment variables and verify they are gitignored

3

Add input validation with zod or similar on all API endpoints

4

Enable Row Level Security on all Supabase tables

5

Add security headers (CSP, CORS, X-Frame-Options) to your config

6

Review authentication flows for proper session handling

Frequently Asked Questions

Why do AI coding tools create security vulnerabilities?

AI coding tools optimize for functionality, not security. They often hardcode secrets, skip input validation, and use permissive database policies because those patterns produce working code fastest.

How much does a security audit cost for a vibe-coded app?

A basic security audit for a typical vibe-coded application starts around $500 and takes 3-5 days. Complex applications with authentication, payments, or sensitive data may cost $1,500-3,000+.

Can I fix security issues myself without hiring an agency?

Many common issues (exposed secrets, missing headers, basic validation) can be self-fixed using security scanners and checklists. However, authentication architecture and complex vulnerabilities benefit from professional review.
