SCA: security update for github.com/argoproj/argo-cd/v2 (GHSA-6jqw-jwf5-rp8h)

medium Tenable Cloud Security Plugin ID 411503

Description

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

 - Argo CD is a declarative continuous deployment framework for Kubernetes. In Argo CD versions prior to 2.3
 (starting at least in v0.1.0, but likely in any version using Helm before 2.3), using a specifically-
 crafted Helm file could reference external Helm charts handled by the same repo-server to leak values, or
 files from the referenced Helm Chart. This was possible because Helm paths were predictable. The
 vulnerability worked by adding a Helm chart that referenced Helm resources from predictable paths. Because
 the paths of Helm charts were predictable and available on an instance of repo-server, it was possible to
 reference and then render the values and resources from other existing Helm charts regardless of
 permissions. While generally, secrets are not stored in these files, it was nevertheless possible to
 reference any values from these charts. This issue was fixed in Argo CD 2.3 and subsequent versions by
 randomizing Helm paths. User's still using Argo CD 2.3 or below are advised to update to a supported
 version. If this is not possible, disabling Helm chart rendering, or using an additional repo-server for
 each Helm chart would prevent possible exploitation. (CVE-2023-40026)
