Remediation

This change fixes findings identified by CodeQL.

Details

Command injection vulnerabilities occur when untrusted data is used to construct a command that is executed by the operating system. An attacker can exploit this vulnerability to execute arbitrary commands on the server, potentially leading to unauthorized access, data leakage, or other security breaches.

This change adds controls to prevent command injection vulnerabilities by sanitizing inputs and/or validating user input to ensure that it does not contain any malicious commands. It also ensures that command arguments cannot be used to inject additional commands.

I have additional improvements ready for this repo! If you want to see them, leave the comment:
