CVE-2020-26979 Information

Description

When a user typed a URL in the address bar or the search bar and quickly hit the enter key a website could sometimes capture that event and then redirect the user before navigation occurred to the desired entered address. To construct a convincing spoof the attacker would have had to guess what the user was typing perhaps by suggesting it. This vulnerability affects Firefox < 84.
