| Doc Text: |
A flaw was found in Argo Workflows. This flaw, a nil pointer dereference in the `rbacAuthorization()` function, affects Single Sign-On (SSO) users. When `SSO_DELEGATE_RBAC_TO_NAMESPACE` is enabled, an authenticated SSO user whose claims match a namespace-level Role-Based Access Control (RBAC) rule but not an SSO-namespace rule can trigger a system panic. This can lead to a Denial of Service (DoS) for the affected system.
