CVE-2026-72633Network attack vectorHinoki check available

Monitoring loss via improperly authorized task stop

Published Sep 1, 2026 · Updated Sep 1, 2026

Incorrect authorization in Kibana 9.1.0 through 9.4.5 and 9.5.0 through 9.5.1 allows remote authenticated users to stop privilege monitoring. Entity Analytics access controls permit read-level Security users to stop the recurring Privilege Monitoring engine task for a space. The engine must have been initialized; stopping it suppresses new privileged-user monitoring data while Kibana continues to report a healthy state.
