CVE-2020-26979
To construct a convincing spoof the attacker would have had to guess what the user was typing, perhaps by suggesting it.
MEDIUM 6.1EPSS 0.72%
Does this matter?
Lower severity and a low EPSS score (0.72%). Track it; it rarely justifies an emergency change on its own.
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.
