Summary

A document disclosure flaw exists in Elasticsearch versions prior to 7.11.2 and 6.8.15 that compromises Document and Field Level Security. During specific cross-cluster search queries, the security permissions are not appropriately maintained, leading to unintended access. This may allow attackers to uncover the existence of sensitive documents and indices, even if they should not have permissions to view them, significantly raising the risk of data exposure.

Affected Version(s)

Elasticsearch before 7.11.2 and 6.8.15
