MEDIUM 6.5EPSS 0.58%

Does this matter?

Lower severity and a low EPSS score (0.58%). Track it; it rarely justifies an emergency change on its own.

Description

When exiting fullscreen mode, an iframe could have confused the browser about the current state of fullscreen, resulting in potential user confusion or spoofing attacks. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
