CVE-2026-72664— Missing Authorization in Kibana Leading to Unauthorized Execution of Endpoint Response Actions

Quick assessment

Affected
Elastic Kibana
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Elastic Kibana是荷兰Elastic公司开源的一个视觉化仪表板。 Elastic Kibana 8.9.0至8.19.19版本和9.0.0至9.4.4版本存在授权问题漏洞，该漏洞源于授权缺失，可能导致仅拥有检测规则编写权限的Kibana用户将自动化的端点响应操作与检测规则关联，即使未授予该用户控制这些功能（主机隔离、进程操作和执行操作）的专属端点响应操作权限，当此类规则生成警报时，相关响应操作也会对匹配的主机执行，从而导致未经授权执行Elastic Defend响应操作。

Vulnerability Title
Missing Authorization in Kibana Leading to Unauthorized Execution of Endpoint Response Actions
Source: CVE Program / CVE List V5
Vulnerability Description
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.
