Description Huzaifa S. Sidhpurwala 2017-04-19 06:27:43 UTC

A mechanism to inject static HTML into the RSS reader preview page due to a failure to escape characters sent as URL parameters for a feed's <code>TITLE</code> element. This vulnerability allows for spoofing but no scripted content can be run.
