• URGENT: Change default admin password from admin123 to secure password
• URGENT: Implement proper environment variable management
• URGENT: Add .env to .gitignore and commit
• URGENT: Document secret rotation procedures

Impact: Complete system compromise if repository accessed by unauthorized users

Fix CORS Configuration

• URGENT: Change allow_origins=["*"] to specific domains in app/main.py:65
• URGENT: Configure proper CORS headers for production
• URGENT: Test CORS configuration with frontend domains

Impact: Prevents XSS, CSRF, and data theft vulnerabilities

Implement Input Validation

• URGENT: Add file type validation for upload endpoints

• URGENT: Implement path traversal protection in file operations
• URGENT: Add CSV import data validation and sanitization
• URGENT: Validate all user inputs with Pydantic schemas

Impact: Prevents file upload attacks and data injection
