The Register has reported that Google’s Chromium developers team has proposed a way to establish web applications direct network connections.
The Raw Sockets API, which may end up being renamed the Direct Sockets API, represents an attempt to give browser apps networking capabilities that aren’t possible via data transport options like HTTP, WebSockets and WebRTC. It essentially allows the browser to talk directly to devices and other computers via the network.
This can put web at huge security risks and can be used to heavily violate users’ privacy. Nothing can go wrong except for everything related to users’ security and choices over privacy.
I highly encourage you to get away from Google Chrome and other Chromium-based browsers that follow Google’s path.
