CVE-2026-72654: Elastic Kibana

Medium severity, CVSS 6.5. EPSS: 0.5% chance of exploitation in the next 30 days.

Execution with Unnecessary Privileges (CWE-250) in the Kibana machine learning feature can lead to information disclosure via Privilege Abuse (CAPEC-122). An operation available to users holding only read access to the machine learning feature was performed with an internal service identity rather than the identity of the requesting user. Such a user could therefore receive data from Elasticsearch indices they are not authorized to read. No Elasticsearch cluster or index privileges are required.

Affected products

• Elastic Kibana: from 8.0.0, before 8.19.21 (fixed in 8.19.21); from 9.0.0, before 9.4.6 (fixed in 9.4.6); from 9.5.0, before 9.5.2 (fixed in 9.5.2)
