Release note

ExternalUrl service was integrated with URL Drilldown. This will check every URL Drilldown before executing it against ExternalUrl service to see if user is allowed to navigate to that external URL. By default all external URLs are allowed. To configure external URL policies you need to use externalUrl.policy setting in kibana.yml, an example:

externalUrl.policy:
  - allow: false
    host: danger.google.com
  - allow: true
    host: google.com
    protocol: https
  - allow: true
    host: elastic.co
