CVE-2026-93991
NVD: 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. NVD: 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. OSV: Argo Workflows 4.1.0 through 4.1.3 Cross-Namespace Disclosure via Negated Selector
