In Elasticsearch versions before 7.11.2 and 6.8.15 a document disclosure
flaw was found when Document or Field Level Security is used. Search
queries do not properly preserve security permissions when executing
certain cross-cluster search queries. This could result in the search
disclosing the existence of documents the attacker should not be able to
view. This could result in an attacker gaining additional insight into
potentially sensitive indices.
