CVE-2026-72671Network attack vector

Model space assignment modification via incomplete privilege check

Published Aug 13, 2026 · Updated Aug 13, 2026

Missing authorization in Kibana 8.0.0 through 8.19.19 and 9.0.0 through 9.4.4 allows remote authenticated users to alter model space assignments. The remove-from-current-space capability accepts trained-model saved objects but checks only anomaly-detection and data-frame-analytics creation privileges. Exploitation requires Machine Learning to be enabled and a custom role with that unusual privilege combination; it removes the model only from one space and does not delete the model.
