Critical Vulnerability Information 1. SQL Injection Risk - Multiple functions in the file directly use user-supplied data for database operations, such as , , etc. - For example, in the function: If and are not strictly validated and sanitized, this could lead to SQL injection attacks. 2. File Operation Risk - In the function, the user-supplied parameter is directly used to create a file: If contains malicious paths or special characters, it may result in arbitrary file creation or overwriting. 3. Insufficient Exception Handling - Exception handling in multiple functions merely throws exceptions without detailed error logging or user-friendly error messages, which can complicate debugging and security auditing. 4. Missing Access Control - There is no apparent permission-checking mechanism in the code. Any user calling these functions could potentially perform sensitive operations, such as adding news items or creating plants. 5. Hardcoded Paths - Critical information such as file paths and database table names is hardcoded in the code. Any modification requires changing the source code, increasing maintenance complexity and potential security risks. Recommendations Strictly validate and sanitize all user inputs to prevent SQL injection and file operation risks. Enhance exception handling by logging detailed error information and providing user-friendly error messages. Implement access control mechanisms to ensure only authorized users can perform sensitive operations. Avoid hardcoding critical information; use configuration files or environment variables for management.
