CWE
- CWE-863 - Incorrect Authorization
Summary
Incorrect Authorization (CWE-863) in Kibana can lead to privilege escalation via Input Data Manipulation (CAPEC-153). Elasticsearch cluster privilege declarations originating from integration packages were not validated before being used to mint credentials for enrolled Elastic Agents. A user holding Fleet management privileges could therefore cause every Elastic Agent on a targeted policy to receive a credential carrying arbitrarily elevated Elasticsearch cluster privileges, up to and including full cluster administration.

- CWE-862 - Missing Authorization
Summary
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.
