Kibana CALE Unauthorized Exec of Elastic Defend Actions
CVE-2026-72664 Published on August 13, 2026
Missing Authorization in Kibana Leading to Unauthorized Execution of Endpoint Response Actions
Missing Authorization (CWE-862) in Kibana can lead to unauthorized execution of Elastic Defend response actions on managed hosts via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). A Kibana user who holds only detection rule authoring privileges for the Elastic Security solution can associate automated endpoint response actions with a detection rule, even though the dedicated Endpoint response action privileges that govern those capabilities (host isolation, process operations, and execute operations) have not been granted to that user. When such a rule generates alerts, the associated response actions are carried out against the matching hosts.
