Estado: Pendiente de análisisMedia (4.3)—

Missing Authorization in Kibana Leading to Unauthorized Modification of Data / Missing Authorization (CWE-862) in Kibana can lead to unauthorized modification of data via Privilege Abuse (CAPEC-122). An authenticated user holding Security read-level access in a single Kibana space could trigger Entity Analytics migration operations that perform privileged writes across all Kibana spaces, regardless of that user's actual access scope.
