Description
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to improperly imposed security restrictions on the API key for the cross-cluster search. If a cross-cluster API key restricts search for a given index using the query or the field_security parameter, and the same cross-cluster API key also grants replication for the same index, the search restrictions are not enforced during cross cluster search operations and search results may include documents and terms that should not be returned. A remote user can gain access to potentially sensitive information.
Remediation
