How to scan AI-generated code for security vulnerabilities

Published by CyberLens AI. Last updated .

AI-generated code ships fast but carries predictable security gaps: outdated dependencies, hardcoded secrets, missing authorization, and insecure patterns reproduced from older training data.

This guide walks through a five-step scanning workflow — npm audit, gitleaks, Semgrep, Trivy, and a website scan — that catches the highest-risk issues before deployment.

Common risks in AI-generated code

AI models reproduce the most common patterns from their training data, which includes older, less secure code.

  • Vulnerable dependencies — models suggest popular but outdated package versions
  • Hardcoded secrets — API keys and tokens inlined as placeholder values
  • Missing authentication — API routes generated without authorization middleware
  • SQL injection via string templates — parameterized queries replaced with interpolation
  • Unsafe defaults — CORS set to *, debug mode enabled, permissive file uploads

Five-step scanning workflow

The full workflow runs in under ten minutes and covers the most common risk categories.

  • Step 1: npm audit (or pip-audit) for vulnerable dependencies
  • Step 2: gitleaks or truffleHog for hardcoded secrets — run before the first push
  • Step 3: Semgrep with p/owasp-top-ten for insecure code patterns
  • Step 4: Trivy for container images and IaC files
  • Step 5: CyberLens AI website scan for TLS, headers, and browser protections

Questions and answers

Does AI-generated code have more vulnerabilities than hand-written code?

Not inherently, but the risks are different. AI models reproduce the most common patterns in their training data, which includes older, less secure code. The main risks are outdated dependencies, hardcoded placeholders, missing authorization, and SQL injection — all fixable with a basic scanning workflow.

What is the single most important scan to run on AI-generated code?

A secret scan (gitleaks or truffleHog) before the first push to a remote repository. Hardcoded credentials are the fastest path from AI-generated code to a real incident.

Do I need to pay for security scanning of AI-generated code?

No. The core workflow — npm audit, gitleaks, Semgrep with the OWASP Top 10 ruleset, and Trivy — is entirely free and open source. CyberLens AI also offers a free no-signup website scan for the deployed application.

Can I automate AI-generated code scanning in CI/CD?

Yes. All four tools (npm audit, gitleaks, Semgrep, Trivy) have GitHub Actions integrations and run in sequence on every push and pull request with no paid plan required.

Does scanning AI-generated code replace a security review?

No. Automated scanning catches reproducible patterns but misses business-logic flaws and access control design issues. For anything handling user data or payments, combine automated scanning with a manual review of authentication and authorization flows.
