Title
Execution with Unnecessary Privileges in Kibana Leading to reading index data beyond their direct Elasticsearch RBAC scope
Summary
Execution with Unnecessary Privileges (CWE-250) in Kibana’s Fleet plugin debug route handlers can lead reading index data beyond their direct Elasticsearch RBAC scope via Privilege Abuse (CAPEC-122). This requires an authenticated Kibana user with Fleet sub-feature privileges (such as agents, agent policies, and settings management).
