Description

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.
