NVD Description

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

Permission prompts for opening external schemes were only shown for <code>ContentPrincipals</code> resulting in extensions being able to open them without user interaction via <code>ExpandedPrincipals</code>. This could lead to further malicious actions such as downloading files or interacting with software already installed on the system. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.
