Elasticsearch Security versions 6.4.0 to 6.4.2 contain an error in the way
request headers are applied to requests when using the Active Directory,
LDAP, Native, or File realms. A request may receive headers intended for
another request if the same username is being authenticated concurrently;
when used with run as, this can result in the request running as the
incorrect user. This could allow a user to access information that they
should not have access to.
