Описание
Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. From 3.6.5 to 4.0.4, an unchecked array index in the pod informer's podGCFromPod() function causes a controller-wide panic when a workflow pod carries a malformed workflows.argoproj.io/pod-gc-strategy annotation. Because the panic occurs inside an informer goroutine (outside the controller's recover() scope), it crashes the entire controller process. The poisoned pod persists across restarts, causing a crash loop that halts all workflow processing until the pod is manually deleted. This vulnerability is fixed in 4.0.5 and 3.7.14.
A flaw was found in Argo Workflows, an open-source system for managing tasks in Kubernetes. An attacker with appropriate permissions can trigger a system-wide crash by submitting a specially crafted workflow pod with a malformed annotation. This vulnerability leads to a persistent Denial of Service (DoS), preventing all workflow processing until manual intervention removes the poisoned pod.
