Does anyone know or can see an actual concrete security concern with the current implementation of LAN mode?

https://github.com/Doridian/OpenBambuAPI/blob/main/mqtt.md

Right now, the printer's local MQTT server can only be accessed from the local IP using an 8 digit password obtained through through the physical display.

I can't personally see any fundamental issue with this design assuming the implementation is correct, but I'm curious if others can.
