Does this matter?
Lower severity and a low EPSS score (1.39%). Track it; it rarely justifies an emergency change on its own.
Description
When constructing a permission prompt for WebRTC, a URI was supplied from the content process. This URI was untrusted, and could have been the URI of an origin that was previously granted permission; bypassing the prompt. This vulnerability affects Firefox < 78.
