JSON

Punycode format text will be displayed for entire qualified international
domain names in some instances when a sub-domain triggers the punycode
display instead of the primary domain being displayed in native script and
the sub-domain only displaying as punycode. This could be used for limited
spoofing attacks due to user confusion. This vulnerability affects Firefox
< 57.
