Compromised key reverse access

Title might be kinda misleading as i don't have the knowledge to word it better (total newbie).


But i am looking at wireguard to replace tailscale in a homelab and was wondering if the server is compromised and they have access to the private key, is it even possible for them "reverse" hack into my device connected through wireguard? The server will be VLAN isolated as well. So basically


WAN ==> router port forward ==> home server with wireguard <====> phone / pc

Thanks.
