How to fix?

Upgrade org.elasticsearch:elasticsearch to version 5.6.15, 6.6.1 or higher.

Overview

org.elasticsearch:elasticsearch is a Distributed, RESTful Search Engine.

Affected versions of this package are vulnerable to Privilege Escalation. A permission issue was found in Elasticsearch when Field Level Security and Document Level Security are disabled and the _aliases, _shrink, or _split endpoints are used .

If the elasticsearch.yml file has xpack.security.dls_fls.enabled set to false, certain permission checks are skipped when users perform one of the actions mentioned above, to make existing data available under a new index/alias name. This could result in an attacker gaining additional permissions against a restricted index.
