A flaw was found in Kibana. This issue occurs due to Kibana not sanitizing document fields containing HTML snippets. An attacker with the ability to write documents to an elasticsearch index could inject HTML. When the Discover app highlighted a search term containing the HTML, it would be rendered for the user.
