Security updates

edit

In Kibana 7.8.1 and earlier, there is a denial of service (DoS) flaw in Timelion. Attackers can construct a URL that when viewed by a Kibana user, the Kibana process consumes large amounts of CPU and becomes unresponsive, CVE-2020-7016.

You must upgrade to 7.8.1. If you are unable to upgrade, set timelion.enabled to false in your kibana.yml file to disable Timelion.
In all Kibana versions, region map visualizations contain a stored XSS flaw. Attackers that can edit or create region map visualizations can obtain sensitive information or perform destructive actions on behalf of Kibana users who view the region map visualization, CVE-2020-7017.

You must upgrade to 7.8.1. If you are unable to upgrade, set xpack.maps.enabled, region_map.enabled, and tile_map.enabled to false in kibana.yml to disable map visualizations.
