By using a form with a data URI it was possible to gain access to the
privileged JSONView object that had been cloned into content. Impact from
exposing this object appears to be minimal, however it was a bypass of
existing defense in depth mechanisms. This vulnerability affects Firefox <
70, Thunderbird < 68.2, and Firefox ESR < 68.2.
