Quick assessment

Affected
Apache Software Foundation Apache DolphinScheduler
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.

Apache DolphinScheduler 存在一个授权漏洞，允许已认证的非管理员用户获取本应由管理员管理的集群配置中的 Kubernetes 配置数据（kubeconfig）。泄露的 kubeconfig 数据包含凭据，攻击者可能利用这些凭据绕过 DolphinScheduler，直接访问 Kubernetes API。 该漏洞的影响程度取决于所泄露凭据的权限范围。如果 kubeconfig 提供 cluster-admin 或具有广泛特权的服务账号访问权限，攻击者可能读取 Kubernetes Secret

Vulnerability Title
Apache DolphinScheduler: Missing Authorization Checks Allow Non-Admin Users to Retrieve Kubernetes Credentials
Source: CVE Program / CVE List V5
Vulnerability Description
An authorization vulnerability in Apache DolphinScheduler allows authenticated non-admin users to retrieve Kubernetes configuration data intended for administrator-managed cluster configuration. The exposed kubeconfig data contains credentials that may allow users to authenticate directly to the Kubernetes API outside DolphinScheduler. The impact depends on the permissions granted to the disclosed credentials. If the kubeconfig provides cluster-admin or broadly privileged service-account access, an attacker may read Kubernetes Secrets, create pods, and establish persistent access to the cluster. This issue affects Apache DolphinScheduler: from 3.2.0 before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.
