The code does not properly handle errors, which can lead to potential security vulnerabilities. For example, in the 'finally' block, there is a failure to clean up temporary files if deletion fails.
Impact:
An attacker could exploit this by uploading malicious files or performing other unauthorized actions due to improper error handling and lack of logging.
Mitigation:
Implement proper error handling with detailed logging. Ensure that all file operations are wrapped in try-except blocks, and provide clear feedback for errors during cleanup processes.
