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8.19.18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Kibana存储的Observability Onboarding流程状态未绑定到创建流程的用户，且读取和更新该状态的路由未验证所有权，可能导致经过身份验证且具有通用读取权限的用户发现其他用户的Onboarding流程、读取其状态并写入任意进度数据，篡改的流程还可能导致所有者的Onboarding视图出现服务器错误

Vulnerability Title
Missing Authorization in Kibana Leading to Cross-User Information Disclosure and Data Tampering
Source: CVE Program / CVE List V5
Vulnerability Description
The state that Kibana stores for an Observability Onboarding flow is not bound to the user who created the flow, and the routes that read and update that state do not verify ownership. An authenticated user who holds only generic read access to the space can therefore discover the onboarding flows of other users, read their onboarding state, and write arbitrary progress data into them. A tampered flow can also cause the owner's onboarding view to fail with a server error.
