## Overview

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).

## Affected

- `kibana >= 8.0.0, < 8.19.14`
- `kibana >= 9.0.0, < 9.2.8`
- `kibana >= 9.3.0, < 9.3.3`

## Remediation

Upgrade past the affected range:

- `kibana 9.3.3`
