CVE-2026-72665: Kibana lets users run host actions without proper permission
CVE-2026-72665 · published 2 months ago
Summary
In Kibana, a user who can create or test security detection rules can trigger actions on managed computers even if they don't have the rights normally required for those actions. This could expose data from those computers or cause unwanted changes to them. Review and limit who can author or evaluate detection rules, and ensure proper access controls are in place for host response features.

Original advisory text
Missing Authorization in Kibana Leading to Unauthorized Execution of Host Response Actions
Missing Authorization (CWE-862) in Kibana can lead to unauthorized execution of Osquery and Elastic Defend response actions on managed hosts via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). A Kibana user who is able to author and evaluate Elastic Security detection rules can cause response actions to be carried out against enrolled agents without holding the Osquery live query privileges or the Elastic Defend response action privileges that normally govern those capabilities. Depending on the response action involved, this can result in disclosure of information from the affected hosts or in unauthorized changes to their state.
