Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
It was identified that if a cross-cluster API key https://www.elastic.co/guide/en/elasticsearch/reference/8.14/security-api-create-cross-cluster-api-key.html#security-api-create-cross-cluster-api-key-request-body  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. This issue only affects the API key based security model for remote clusters https://www.elastic.co/guide/en/elasticsearch/reference/8.14/remote-clusters.html#remote-clusters-security-models  that was previously a beta feature and is released as GA with 8.14.0

Recommended fix High confidence

Elasticsearch 8.14.0 or later

  1. 1. Plan and schedule an Elasticsearch upgrade to version 8.14.0 or later
  2. 2. Back up all your Elasticsearch data and cluster state before upgrading
  3. 3. Review Elastic's upgrade documentation at https://www.elastic.co/guide/en/elasticsearch/reference/8.14/upgrading-elasticsearch.html
  4. 4. Perform a rolling upgrade following Elastic's recommended upgrade procedure
  5. 5. After upgrade, verify that cross-cluster API key search restrictions are properly enforced by testing query and field_security parameters
  6. 6. Confirm that cross-cluster search operations now correctly apply the restricted search filters
Caveat Review 8.14.0 release notes for any breaking changes; note that the cross-cluster API key feature was promoted from beta to GA in this release
