MLRun through 1.11.0 contains a server-side request forgery vulnerability in the WebhookNotification handler that allows authenticated users to make the API server send arbitrary HTTP requests to internal addresses. Attackers can update a run with a malicious webhook notification that executes when the run reaches a terminal state, enabling requests to internal services, Kubernetes APIs, or cloud metadata endpoints from within the cluster.
