If a page is loaded from an original site through a hyperlink and contains a redirect to a “data:text/html” URL, triggering a reload will run the reloaded “data:text/html” page with its origin set incorrectly. This allows for a cross-site scripting (XSS) attack. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
