SCA: security update for helm.sh/helm/v3, helm.sh/helm/v4 (GHSA-hr2v-4r36-88hr)

medium Tenable Self-Hosted Container Security Plugin ID 440164

Description

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

 - Helm is a package manager for Charts for Kubernetes. In Helm versions <=3.20.1 and <=4.1.3, a specially
 crafted Chart will cause helm pull --untar [chart URL | repo/chartname] to write the Chart's contents to
 the immediate output directory (as defaulted to the current working directory; or as given by the
 --destination and --untardir flags), rather than the expected output directory suffixed by the chart's
 name. This vulnerability is fixed in 3.20.2 and 4.1.4. (CVE-2026-35206)

Solution

Update the helm.sh/helm/v3 library and its related packages to version 3.20.2 or later.
