CVE-2026-72671: Missing Authorization in Kibana Leading to Unauthorized Modification of Machine Learning Trained Model Space Assignments
- Severity: medium (CVSS 4.3 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.3% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-08-13 · updated 2026-09-04
- Weakness: CWE-862
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.
Affected products
- Kibana: before 8.19.20; from 9.0.0 before 9.4.5 — fixed in 8.19.20, 9.4.5
How to fix
Upgrade to a fixed version: Kibana 8.19.20, 9.4.5. Check the vendor advisory for mitigations.
