parseusbs before 1.9 contains an OS command injection vulnerability where the volume listing path argument (-v flag) is passed unsanitized into an os.popen() shell command with ls, allowing arbitrary command injection via crafted volume path arguments containing shell metacharacters. An attacker can provide a crafted volume path via the -v flag that injects arbitrary commands during volume content enumeration.
