Description Huzaifa S. Sidhpurwala 2017-04-19 05:46:41 UTC 
If a page is loaded from an original site through a hyperlink and contains a redirect to a <code>data:text/html</code> URL with defined <code>Location</code> header; triggering a reload will run the reloaded <code>data:text/html</code> page with its origin set incorrectly. This allows for a cross-site scripting (XSS) attack.
