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.

Affected products

Apache Software Foundation Apache DolphinScheduler: from 3.1.0 before 3.4.3 — fixed in 3.4.3

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache DolphinScheduler 3.4.3. Check the vendor advisory for mitigations.
