Security updates

Elasticsearch versions before 7.10.0 and 6.8.14 have an information disclosure issue when audit logging and the emit_request_body option are enabled. The Elasticsearch audit log could contain sensitive information, such as password hashes or authentication tokens. This could allow an Elasticsearch administrator to view these details. You must upgrade to Elasticsearch version 6.8.14 to obtain the fix. CVE-2020-7021
