Details

(Whiteboard: [domsecurity-backlog2])

PContent::PContentPermissionRequest accepts a principal from the content process and uses it to request and store permissions. A rogue content process could supply a fraudulent principal and potentially trick the user into granting access for a different domain. Alternately, I believe the Content Process could supply a principal the user has granted persistent access to and thus bypass the permission check. We should validate the principal supplies is valid for the origins the content process is hosting.
