CVE-2026-72630— Incorrect Authorization in Kibana Fleet Leading to Privilege Escalation

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 8.19.0至8.19.19版本、9.0.0至9.4.4版本和9.5.0版本存在授权问题漏洞，该漏洞源于授权检查错误，即更新集成策略时，对集成策略的许可限制错误地基于存储策略中的集成而非更新时提供的替换集成进行验证，可能导致拥有Elastic Defend端点策略管理权限的已认证用户将端点策略转换为不同集成的策略，并同时提供该集成的配置，从而导致权限提升。

Vulnerability Title
Incorrect Authorization in Kibana Fleet Leading to Privilege Escalation
Source: CVE Program / CVE List V5
Vulnerability Description
Incorrect Authorization (CWE-863) in Kibana Fleet can lead to privilege escalation via Privilege Abuse (CAPEC-122). Fleet restricts some callers to managing integration policies for one specific integration. When an existing integration policy was updated, that restriction was evaluated against the integration recorded on the stored policy rather than against the replacement integration supplied with the update. An authenticated user holding only the Elastic Defend endpoint policy management privilege was therefore able to convert an endpoint policy they administer into a policy for a different integration, and to supply that integration's configuration at the same time.
