Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Elasticsearch versions 8.10.0 up to but not including 8.13.0 are affected by an incorrect authorization issue in the API key based Remote Cluster Security model, a feature that is in Beta. An attacker holding a valid API key for a remote cluster that uses this feature can read arbitrary documents from any index on that cluster by using the Elasticsearch custom transport protocol. The REST API endpoints are not affected. Upgrade to Elasticsearch 8.13.0 or later.
