Kibana Reporting plugin version 2.4.0 is vulnerable to a CSRF vulnerability that could allow an attacker to generate superfluous reports whenever an authenticated Kibana user navigates to a specially-crafted page.
The Reporting feature in X-Pack in versions prior to 5.5.2 and standalone Reporting plugin versions versions prior to 2.4.6 had an impersonation vulnerability. A user with the reportinguser role could execute a report with the permissions of another reporting user, possibly gaining access to sensitive data.
