NVD Description

Note: Versions mentioned in the description apply only to the upstream argo-workflows-fips-4.1 package and not the argo-workflows-fips-4.1 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Argo Workflows versions 4.1.0 through 4.1.3 contain an authorization bypass vulnerability in ListArchivedWorkflows that fails to apply cluster-scoped access review when the metadata.namespace field selector uses the NotEquals operator. Attackers with namespace-scoped list permissions can use a negated namespace field selector to retrieve archived workflows from all other namespaces, exposing spec arguments, parameter values, and annotations.
