Here’s a concise analysis of the code: 1. **Database Security**: Hardcoding the database password poses a security risk. Using environment variables is recommended, though ideally, a secure secrets manager should be used. 2. **SQL Injection**: Directly inserting user input into SQL queries is vulnerable to SQL injection. Parameterized queries were introduced to mitigate this. 3. **Error Handling and Logging**: Errors are currently printed to the console, which is not suitable for production. Using Python’s `logging` module allows for better error tracking and centralized logging. 4. **File Upload Handling**: File uploads use the original filename, risking duplication and issues with special characters. Generating unique filenames (e.g., with UUIDs) provides a safer approach. 5. **Database Connection Management**: Managing connections manually is error-prone. Using context managers for cursor operations ensures connections are closed automatically. 6. **Unused Imports**: The `send_file` import is unused and can be removed to keep the code clean. These changes improve security, reliability, and maintainability.
