AI-suggested

Users of affected versions 9.4.0 and 9.5.0 should monitor Elastic's advisories for updates and consider restricting access to Kibana Agent Builder functionality until a fix is available.

Description

Kibana Agent Builder determines whether a caller owns a private agent by comparing a stable user identifier when one is recorded, and falling back to a comparison of the username when it is not. A username is not unique across Elasticsearch authentication realms, so two distinct principals that share a username in different realms are treated as the same owner. This discloses the configuration and instructions of an agent the caller does not own, and allows that agent to be altered or removed.
