Problema

Found subprocess function Popen with shell=True. This is dangerous because this call will
spawn the command using a shell process. Doing so propagates current shell settings and
variables,
which makes it much easier for a malicious actor to execute commands. Use shell=False
instead.

Contexto original

def run_backup(user_supplied_path):
    # Vulnerability: command injection with subprocess.Popen and shell=True.
    return subprocess.Popen("tar czf backup.tgz " + user_supplied_path, shell=True)

Fix aplicado

import subprocess

def run_backup(user_supplied_path):
    # Vulnerability: command injection with subprocess.Popen and shell=True.
    # Fixed: changed shell=True to shell=False and used shlex.split to safely handle user input.
    import shlex
    command = ["tar", "czf", "backup.tgz", shlex.quote(user_supplied_path)]
    return subprocess.Popen(command, shell=False)
