Security Review

Perform a comprehensive security review of $ARGUMENTS:

Check for OWASP Top 10

1. Injection (SQL, NoSQL, OS Command, LDAP)

   • Look for string concatenation in queries
   • Check for parameterized queries / prepared statements
   • Check for ORM misuse (raw queries)

2. Broken Authentication

   • Check password hashing (bcrypt/scrypt/argon2, not MD5/SHA1)
   • Check session management and token expiry
   • Look for hardcoded credentials

3. Sensitive Data Exposure

   • Check for secrets in code (API keys, passwords, tokens)
   • Verify encryption at rest and in transit
   • Check logging for PII/sensitive data leaks

4. XML External Entities (XXE)

   • Check XML parser configuration
   • Verify external entity processing is disabled

5. Broken Access Control

   • Check authorization on every endpoint
   • Look for IDOR vulnerabilities
   • Verify RBAC/ABAC implementation

6. Security Misconfiguration

   • Check HTTP headers (CORS, CSP, HSTS)
   • Look for debug mode in production
   • Check default credentials

7. Cross-Site Scripting (XSS)

   • Check output encoding/escaping
   • Look for dangerouslySetInnerHTML, innerHTML, | safe
   • Verify CSP headers

8. Insecure Deserialization

   • Check for untrusted deserialization
   • Verify input validation before deserialization

9. Using Components with Known Vulnerabilities

   • Check for outdated dependencies
   • Run npm audit / pip audit / cargo audit

10. Insufficient Logging & Monitoring

    • Verify auth events are logged
    • Check for sensitive data in logs

Output Format

Provide findings as:

• CRITICAL: Exploitable vulnerabilities
• HIGH: Likely exploitable or high-impact issues
• MEDIUM: Defense-in-depth improvements
• LOW: Best practice recommendations

For each finding: describe the issue, show the vulnerable code, explain the risk, and provide the fix.
