Do not file a public issue for a vulnerability in the CLI or in scripts/install.sh.
Report privately: https://github.com/nyxsky404/vmup/security/advisories/new
Include the affected version (vmup --version), the command, and enough detail to reproduce.
vmup copies files you select onto a host you already SSH into. It does not open inbound ports. Treat remote batches as sensitive until TTL deletes them.
