Description Robert Frohl 2021-08-20 09:03:16 UTC

CVE-2021-29987

After requesting multiple permissions, and closing the first permission panel,
subsequent permission panels will be displayed in a different position but still
record a click in the default location, making it possible to trick a user into
accepting a permission they did not want to. *This bug only affects Firefox on
Linux. Other operating systems are unaffected.*. This vulnerability affects
Firefox < 91 and Thunderbird < 91.
