Windows VM having limited privileges and no internet : dangerous ?

[kalpana]

Hello,

I like the possibility to start a Windows virtual machine under Ubuntu with a common remote volume to share data.

Imagine this setup : Windows 10 VM, user account with limited privileges, remote desktop activated, no internet access at all, smb access to one distant volume on a server. An administrator account also exists with a furiously long password. VM host (Ubuntu 20 or 22) has access to internet and local network.

Daily use this VM with Remmina from other machine on the local network (user account only) : is it dangerous ?

Thank you.
