What is CVE-2026-72671?
CVE-2026-72671 is a medium-severity missing authorization vulnerability in Elastic Kibana, published on 13 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
A Kibana Machine Learning capability that removes a saved object from the current space accepts machine learning trained models as a target, but it verifies only the privileges that apply to anomaly detection jobs and data frame analytics jobs. A user whose role grants create anomaly detection jobs and data frame analytics jobs without the trained model privilege can therefore remove a trained model from a space. The model itself is not deleted and remains available in its other spaces, and the change can be reversed by a suitably privileged user.
Weakness: CWE-862
