CVE-2024-23445Network attack vector

Restricted data disclosure via cross-cluster key overlap

Published Jun 12, 2024 · Updated Oct 31, 2024

Incorrect authorization in Elastic Elasticsearch 8.10.0 through 8.13.4 allows remote authenticated users to read restricted search data. When one cross-cluster API key grants replication and restricted search access to the same index, cross-cluster search omits query or field-security restrictions. Exploitation requires the API-key remote-cluster model and returns documents or terms outside the key's intended search scope.
