NexTor IP Changer is a command-line tool that leverages the Tor network to periodically rotate a user's IP address. Versions prior to 2.0.0 execute privileged system commands using "sudo" and "shell=True" directly inside application logic. In environments where passwordless sudo ("NOPASSWD") is enabled, privileged commands may execute silently without explicit user confirmation. Version 2.0.0 fixes the issue.
