To fix the problem, we need to ensure that the user-provided inputs are validated against a predefined allowlist or sanitized before being used in the command. This can be achieved by creating a set of allowed values for user, tags, type, and productId, and checking the inputs against these sets before constructing the command. If the inputs are not in the allowlist, the function should raise an error or handle it appropriately.

To fix the problem, we should avoid constructing the command string by concatenating user inputs directly. Instead, we can pass the user inputs as arguments to the Python script using a list, which
subprocess.Popencan safely handle without invoking the shell. This approach ensures that the inputs are treated as arguments rather than executable code.instasubprocessfunction to construct the command as a list of arguments.subprocess.Popencall to use this list withoutshell=True.Suggested fixes powered by Copilot Autofix.
