CVE-2026-72644: Elastic Kibana

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

Uncaught Exception (CWE-248) in Kibana can lead to a denial of service via Input Data Manipulation (CAPEC-153). An authenticated user holding only the low-privileged feature access required to use the Observability AI Assistant can submit a specially crafted request that produces an unhandled error condition, terminating the Kibana process and denying service to all users and spaces on that instance until it is restarted.

Affected products

• Elastic Kibana: from 9.1.7, before 9.4.5 (fixed in 9.4.5); version 9.5.0 only
