high Tenable Cloud Security Plugin ID 438661

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 2.9.0 to before 4.0.2 and 3.7.11, A user who can submit Workflows can completely bypass
 all security settings defined in a WorkflowTemplate by including a podSpecPatch field in their Workflow
 submission. This works even when the controller is configured with templateReferencing: Strict, which is
 specifically documented as a mechanism to restrict users to admin-approved templates. The podSpecPatch
 field on a submitted Workflow takes precedence over the referenced WorkflowTemplate during spec merging
 and is applied directly to the pod spec at creation time with no security validation. This vulnerability
 is fixed in 4.0.2 and 3.7.11. (CVE-2026-31892)

Solution

Update the github.com/argoproj/argo-workflows/v3 library and its related packages to version 3.7.11 or later.
