以下是这段漏洞描述的中文翻译： Kibana 机器学习功能中存在“以不必要的权限执行”（CWE-250）问题，可能导致通过“权限滥用”（CAPEC-122）造成信息泄露。 该漏洞中，一个仅拥有机器学习功能只读权限的用户所执行的操作，实际是使用内部服务身份而非请求用户的身份来执行的。因此，这类用户可能会获取到其未获授权读取的 Elasticsearch 索引中的数据。此漏洞的利用不需要任何 Elasticsearch 集群或索引权限。 --- 翻译要点解析： 1. CWE-250: Execution with Un

Vulnerability Title
Execution with Unnecessary Privileges in Kibana Leading to Information Disclosure
Source: CVE Program / CVE List V5
Vulnerability Description
Execution with Unnecessary Privileges (CWE-250) in the Kibana machine learning feature can lead to information disclosure via Privilege Abuse (CAPEC-122). An operation available to users holding only read access to the machine learning feature was performed with an internal service identity rather than the identity of the requesting user. Such a user could therefore receive data from Elasticsearch indices they are not authorized to read. No Elasticsearch cluster or index privileges are required.
