SCA: security update for github.com/argoproj/argo-workflows/v3, github.com/argoproj/argo-workflows/v4 (GHSA-5jv8-h7qh-rf5p)

high Tenable Cloud Security Plugin ID 440793

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on
 Kubernetes. From 3.6.5 to 4.0.4, an unchecked array index in the pod informer's podGCFromPod() function
 causes a controller-wide panic when a workflow pod carries a malformed workflows.argoproj.io/pod-gc-
 strategy annotation. Because the panic occurs inside an informer goroutine (outside the controller's
 recover() scope), it crashes the entire controller process. The poisoned pod persists across restarts,
 causing a crash loop that halts all workflow processing until the pod is manually deleted. This
 vulnerability is fixed in 4.0.5 and 3.7.14. (CVE-2026-40886)

Solution

Update the github.com/argoproj/argo-workflows/v3 library and its related packages to version 3.7.14 or later.
