SCA: security update for github.com/argoproj/argo-cd/v2 (GHSA-fwr2-64vr-xv9m)

critical Tenable Cloud Security Plugin ID 414740

Description

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

 - Argo CD is a declarative continuous deployment for Kubernetes. Argo CD Cluster secrets might be managed
 declaratively using Argo CD / kubectl apply. As a result, the full secret body is stored
 in`kubectl.kubernetes.io/last-applied-configuration` annotation. pull request #7139 introduced the ability
 to manage cluster labels and annotations. Since clusters are stored as secrets it also exposes the
 `kubectl.kubernetes.io/last-applied-configuration` annotation which includes full secret body. In order to
 view the cluster annotations via the Argo CD API, the user must have `clusters, get` RBAC access.
 **Note:** In many cases, cluster secrets do not contain any actually-secret information. But sometimes, as
 in bearer-token auth, the contents might be very sensitive. The bug has been patched in versions 2.8.3,
 2.7.14, and 2.6.15. Users are advised to upgrade. Users unable to upgrade should update/deploy cluster
 secret with `server-side-apply` flag which does not use or rely on `kubectl.kubernetes.io/last-applied-
 configuration` annotation. Note: annotation for existing secrets will require manual removal.
