For more than a decade, the Internet has remained vulnerable to a class of attacks that uses browsers as a beachhead for accessing routers and other sensitive devices on a targeted network. Now, Google is finally doing something about it.

Starting in Chrome version 98, the browser will begin relaying requests when public websites want to access endpoints inside the private network of the person visiting the site. For the time being, requests that fail won’t prevent the connections from happening. Instead, they’ll only be logged. Somewhere around Chrome 101—assuming the results of this trial run don’t indicate major parts of the Internet will be broken—it will be mandatory for public sites to have explicit permission before they can access endpoints behind the browser.
