CVE-2026-72629 is a high-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
Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to unauthorized cross-space access via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). The result is disclosure of inference output from a trained model in a different space that the user is not authorized to list, read, or use, which exposes the behavior of a model. The same pattern also reached the deployment stop and deployment update operations, allowing an active trained model deployment in another space to be stopped or to have its allocated resources altered.
Weakness: CWE-639
