Summary
OS command injection in NexTor IP Changer (CVE-2026-48098). Confidential information can be exposed externally. Exploitable via sudo.
Original description
The description as published by the source.
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.
