patool before 4.0.6 contains an OS command injection vulnerability on Windows because shell_quote_nt fails to escape cmd.exe metacharacters or embedded double quotes in archive filenames. Attackers can supply crafted filenames like report&calc.gz for single-file formats run with shell=True to execute commands with patool process privileges.
