Description Pedro Sampaio 2018-09-24 20:25:17 UTC 
Elasticsearch Alerting and Monitoring in versions before 6.4.1 or 5.6.12 have an information disclosure issue when secrets are configured via the API. The Elasticsearch _cluster/settings API, when queried, could leak sensitive configuration information such as passwords, tokens, or usernames. This could allow an authenticated Elasticsearch user to improperly view these details.

OpenShift uses Search Guard [1] to protect the affected the _cluster/settings endpoint with certificate based authentication. Therefore none of the OpenShift 3.x versions are affected.
