SCA: security update for github.com/argoproj/argo-workflows/v3, github.com/argoproj/argo-workflows/v4 (GHSA-3775-99mw-8rp4)

high Tenable Cloud Security Plugin ID 441123

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. Prior to versions 3.7.14 and 4.0.5, a user with create Workflow permission can bypass
templateReferencing: Strict to get host network access, switch service accounts, override pod security
context, add tolerations to schedule on control-plane nodes, or enable SA token mounting. This defeats the
stated purpose of the feature. The practical impact depends on what Kubernetes-level controls are in
place. Clusters with PodSecurity admission or OPA/Gatekeeper would independently block some of these (like
hostNetwork). Clusters that rely on Argo's Strict mode as the primary enforcement layer are fully exposed.
This issue has been patched in versions 3.7.14 and 4.0.5. (CVE-2026-42296)

Solution

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