Basically title. Recently I saw a new option in Chromium website permission settings called “allow access to local network” or something like that and I know some antiviruses on Windows that can list all devices connected to the same WiFi network. I’m usually using Firefox based browsers that obviously don’t have the option to disable or enable that access. So can some really invasive websites mine data about my local network, connected devices etc? And if so, what can I do to prevent it except for just disconnecting everything else when visiting such websites?
Is it maybe the case that the setting is for allowing/disallowing you to go to sites on your local network?
For example your router controls at “192.168.1.1” (example address) or a raspberry pi with a selfhosted service like nextcloud etc.
You can probably test whether my claim is true by trying to visit your routers page with the setting enabled vs. disabled. (I am not using Chrome)
I don’t think websites have access to your local network through the browsers javascript engine, but I may be wrong.
