예상 결과:

• ## Code Review Results
•  
• ### Critical Issues Found
• 1. SQL Injection in user_service.py:42
• - Raw string concatenation allows SQL injection
• - FIX: Use parameterized queries with SQLAlchemy ORM
•  
• 2. N+1 Query in post_service.py:78
• - Lazy loading in loop causes 101 queries
• - FIX: Use selectinload(User.posts) for eager loading
•  
• ### Recommended Improvements
• - Consider adding indexes on foreign keys
• - Add input validation for user authentication

예상 결과:

• ## Performance Review
•  
• ### ORM Issues Detected
• - app/models/user.py:15 - Missing eager loading on posts relationship
• - app/services/report.py:42 - Query inside loop causes N+1 pattern
•  
• ### Optimization Suggestions
• - Add joinedload(User.posts) to user query
• - Move query outside loop and use batch loading
• - Consider adding database indexes on frequently queried columns

예상 결과:

• ## Security Audit Results
•  
• ### Injection Risks
• - Broken Authentication: No session timeout configured
• - Insecure Deserialization: pickle.loads() used with untrusted data
•  
• ### XSS Vulnerabilities
• - Template uses innerHTML with user input (3 locations)
•  
• ### Recommendations
• - Replace innerHTML with textContent for user data
• - Use parameterized queries for all database operations
