In Red Hat environments deploying Jenkins, exploitation requires valid credentials and non-default permissions such as Item, View, or Agent configuration rights, which prevents anonymous exploitation. However, because successful exploitation results in full compromise of the underlying container or host running the Jenkins controller, the risk remains elevated in environments with untrusted or multi-tenant users.", "threat_severity": "Important"}
