SCA: security update for helm.sh/helm/v3 (GHSA-q8q8-93cv-v6h8)

medium Tenable Self-Hosted Container Security Plugin ID 431960

Description

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

 - Their is an information disclosure vulnerability in Helm from version 3.1.0 and before version 3.2.0.
 `lookup` is a Helm template function introduced in Helm v3. It is able to lookup resources in the cluster
 to check for the existence of specific resources and get details about them. This can be used as part of
 the process to render templates. The documented behavior of `helm template` states that it does not attach
 to a remote cluster. However, a the recently added `lookup` template function circumvents this restriction
 and connects to the cluster even during `helm template` and `helm install|update|delete|rollback --dry-
 run`. The user is not notified of this behavior. Running `helm template` should not make calls to a
 cluster. This is different from `install`, which is presumed to have access to a cluster in order to load
 resources into Kubernetes. Helm 2 is unaffected by this vulnerability. A malicious chart author could
 inject a `lookup` into a chart that, when rendered through `helm template`, performs unannounced lookups
 against the cluster a user's `KUBECONFIG` file points to. This information can then be disclosed via
 the output of `helm template`. This issue has been fixed in Helm 3.2.0 (CVE-2020-11013)
