MEDIUM 6.5EPSS 0.64%

Does this matter?

Lower severity and a low EPSS score (0.64%). Track it; it rarely justifies an emergency change on its own.

Description

If a user installed an extension of a particular type, the extension could have auto-updated itself and while doing so, bypass the prompt which grants the new version the new requested permissions. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox ESR < 91.6.
