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 9.1.0版本至9.4.4版本存在授权问题漏洞，该漏洞源于使用Kibana内部Elasticsearch账户查询Elastic Defend事件数据，而未验证调用者的Elasticsearch索引权限，可能导致已认证用户检索到包含令牌、凭据等敏感信息的数据。

Vulnerability Title
Incorrect Authorization in Kibana Leading to Disclosure of Elastic Defend Endpoint Event Data
Source: CVE Program / CVE List V5
Vulnerability Description
The Elastic Security capability that suggests existing field values while a user authors endpoint policy artifacts queries Elastic Defend event data with Kibana's internal Elasticsearch account instead of the account of the requesting user. Only Kibana feature privileges are verified, and the caller's Elasticsearch index privileges are not. An authenticated user who holds Elastic Security feature privileges but no read access to the Elastic Defend event indices can therefore retrieve field values from that data, including process command line arguments, which commonly contain tokens, credentials, connection strings, and other sensitive operational detail from protected hosts.
