Last modified
CVE-2026-4498 is a high-severity vulnerability rated 7.7/10 on the CVSS scale. 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).. EPSS estimates a 0.30% chance of exploitation in the next 30 days.
