SCA: security update for github.com/argoproj/argo-workflows/v3, github.com/argoproj/argo-workflows/v4 (GHSA-jcc8-g2q4-9fxq)

high Tenable Self-Hosted Container Security Plugin ID 441125

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, the Webhook Interceptor loads the entire request body into
 memory before authenticating the request or verifying its signature. This occurs on the /api/v1/events/
 endpoint, which is publicly accessible (albeit intended for webhooks). An attacker can send a request with
 an extremely large body (e.g., multiple gigabytes), causing the Argo Server to allocate excessive memory,
 potentially leading to an Out-Of-Memory (OOM) crash and denial of service. This issue has been patched in
 versions 3.7.14 and 4.0.5. (CVE-2026-42294)

Solution

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