NVD Description

Note: Versions mentioned in the description apply only to the upstream thunderbird-debugsource package and not the thunderbird-debugsource package as distributed by RHEL.

When in an endless loop, a website specifying a custom cursor using CSS could make it look like the user is interacting with the user interface, when they are not. This could lead to a perceived broken state, especially when interactions with existing browser dialogs and warnings do not work. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
