Ask Claude to Run a Security Audit of Your Code Against the OWASP Top 10

Security reviews are tedious and easy to skip. Claude reads your code and checks for real vulnerabilities — not theoretical ones, but actual patterns in your files that could be exploited.

"Audit this project for OWASP Top 10 vulnerabilities"

Claude scans your controllers, middleware, queries, templates, and auth logic, then reports findings with specific file paths, line numbers, and fixes. Not a checklist — an actual code review.

You can focus the audit on specific areas:

# Check a specific feature
"Audit the payment flow for security issues — from form submission to charge"

# Focus on a vulnerability class
"Search the entire codebase for SQL injection vulnerabilities"

# Check auth and access control
"Review every route and controller for authorization gaps — can any endpoint be accessed without proper auth?"

# Scan templates for XSS
"Check all Blade templates for unescaped output that could enable XSS"

Claude looks for the things that matter:

• Injection — raw SQL, unparameterized queries, command injection via user input
• Broken auth — missing middleware, weak token validation, session fixation
• Sensitive data exposure — credentials in code, PII in logs, missing encryption
• XSS — unescaped output in templates, innerHTML assignments, dangerouslySetInnerHTML
• Insecure deserialization — unvalidated JSON parsing, pickle loads, eval of user data
• Access control — missing authorization checks, IDOR vulnerabilities, privilege escalation paths

After identifying issues, ask Claude to fix them:

"Fix all the security issues you found, starting with the critical ones"

Claude patches each vulnerability following your framework's security best practices — parameterized queries, CSRF tokens, output escaping, proper auth middleware.

Every codebase has security blind spots — Claude reads every line with the same paranoia, every time you ask.
