NVD Description

Note: Versions mentioned in the description apply only to the upstream argo-workflows-fips-4.0 package and not the argo-workflows-fips-4.0 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.
