SCA: security update for github.com/fluxcd/flux2, github.com/fluxcd/helm-controller, github.com/fluxcd/kustomize-controller (GHSA-vvmq-fwmg-2gjc)

critical Tenable Self-Hosted Container Security Plugin ID 419552

Description

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

 - Flux2 is an open and extensible continuous delivery solution for Kubernetes. Flux2 versions between 0.1.0
 and 0.29.0, helm-controller 0.1.0 to v0.19.0, and kustomize-controller 0.1.0 to v0.23.0 are vulnerable to
 Code Injection via malicious Kubeconfig. In multi-tenancy deployments this can also lead to privilege
 escalation if the controller's service account has elevated permissions. Workarounds include disabling
 functionality via Validating Admission webhooks by restricting users from setting the `spec.kubeConfig`
 field in Flux `Kustomization` and `HelmRelease` objects. Additional mitigations include applying
 restrictive AppArmor and SELinux profiles on the controller’s pod to limit what binaries can be executed.
 This vulnerability is fixed in kustomize-controller v0.23.0 and helm-controller v0.19.0, both included in
 flux2 v0.29.0 (CVE-2022-24817)
