Hi,

this is only a number from the nic driver, not the real speed.
And the speed declaration makes no difference for the guest.

This has nothing to do with security.
It is a number in a driver what exactly do nothing expect showing the speed of the nic.

Is it a bug?
You have a virtual network card without any physical boundaries, so no, this is not a bug. You can transfer data from one VM to another VM on the same host and bridge very fast and internally this uses memory copy, so that you will have a very, very huge bandwidth, which does not comply with normal ethernet standards (remember, there is no real hardware). These "huge" numbers are more an upper limit than guaranteed throughput.

I have here on one server (with only 1 GBE cards) 6 GBit/s between two virtual machines.
