Permission prompts for opening external schemes were only shown for ContentPrincipals resulting in extensions being able to open them without user interaction via ExpandedPrincipals. 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.
