CVE-2026-72633: Elastic Kibana

Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

Incorrect Authorization (CWE-863) in Kibana Entity Analytics can lead to a loss of security monitoring via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user holding only read-level Security feature access, and no Elasticsearch privileges, could stop the recurring Privilege Monitoring engine task for a Kibana space. Privileged user monitoring then stops producing data for that space while the engine continues to report a healthy state to operators.

Affected products

• Elastic Kibana: from 9.1.0, before 9.4.6 (fixed in 9.4.6); from 9.5.0, before 9.5.2 (fixed in 9.5.2)
