    • Security vulnerabilities (OWASP Top 10)
    • Performance concerns
    • Code style and readability
    • Logic errors and bugs
    • Missing error handling
  3. Prioritize feedback from critical to minor
  4. Suggest fixes with concrete code examples

Review Categories

Security

  • SQL injection, XSS, command injection
  • Authentication/authorization flaws
  • Sensitive data exposure
  • Insecure dependencies

Performance

  • N+1 queries
  • Memory leaks
  • Unnecessary computations
  • Missing caching opportunities

Quality

  • DRY violations

### Critical Issues
1. **SQL Injection** (Line 15)
   - Current: `query = f"SELECT * FROM users WHERE email='{email}'"`
   - Fix: Use parameterized queries

### Recommendations
- Add rate limiting
- Implement account lockout
