CVE-2026-28229

Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. Prior to 4.0.2 and 3.7.11, Workflow templates endpoints allow any client to retrieve WorkflowTemplates (and ClusterWorkflowTemplates). Any request with a Authorization: Bearer nothing token can leak sensitive template content, including embedded Secret manifests. This vulnerability is fixed in 4.0.2 and 3.7.11.

Summary		(es) Argo Workflows es un motor de flujo de trabajo de código abierto nativo de contenedor para orquestar trabajos paralelos en Kubernetes. Antes de 4.0.2 y 3.7.11, los endpoints de plantillas de flujo de trabajo permiten a cualquier cliente recuperar WorkflowTemplates (y ClusterWorkflowTemplates). Cualquier solicitud con un token de autorización: Bearer nothing puede filtrar contenido sensible de la plantilla, incluyendo manifiestos de Secret incrustados. Esta vulnerabilidad está corregida en 4.0.2 y 3.7.11.
