CVE-2026-72633— Incorrect Authorization in Kibana Leading to Unauthorized Disabling of Privilege Monitoring

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.

Kibana Entity Analytics 中的不正确授权（CWE-863） 漏洞可能导致安全监控能力受损，其根因是访问未被访问控制列表（ACL）充分约束的功能（CAPEC-1）。 具体而言：一个仅拥有读级别 Security 功能访问权限、且没有 Elasticsearch 权限的已认证用户，可以停止某个 Kibana space 中周期性运行的“权限监控（Privilege Monitoring）”引擎任务。这会导致该 space 的特权用户监控不再产生数据，而监控引擎仍会向运维人员报告其状态为“健康”，从

Vulnerability Title
Incorrect Authorization in Kibana Leading to Unauthorized Disabling of Privilege Monitoring
Source: CVE Program / CVE List V5
Vulnerability Description
Incorrect Authorization (CWE-863) in Kibana Entity Analytics can lead to a loss of security monitoring via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user holding only read-level Security feature access, and no Elasticsearch privileges, could stop the recurring Privilege Monitoring engine task for a Kibana space. Privileged user monitoring then stops producing data for that space while the engine continues to report a healthy state to operators.
