The pull request aims to enhance security by transitioning from unencrypted HTTP to HTTPS, addressing some vulnerabilities, but raises concerns about a potential bug related to user input handling for command execution. Although the shift to a list format for subprocess.call reduces certain command injection risks, it fails to adequately validate or sanitize user input, leaving the system open to unintended behavior. Furthermore, the changes do not comply with established coding standards for input validation and error handling, highlighting the need for these practices to ensure both the security and reliability of the code.
