Description Doran Moppert 2020-11-18 00:44:04 UTC
Searching for a single word from the address bar caused an mDNS request to be sent on the local network searching for a hostname consisting of that string; resulting in an information leak.

*Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*
