Quick assessment

Affected
argoproj argo-cd
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Argo CD 是一款面向 Kubernetes 的声明式 GitOps 持续交付工具。在版本 2.1.0 至 3.3.15、3.4.10、3.5.4 以及 3.6.0-rc2 期间，若运维人员为 Kustomize 构建启用了 选项，则 配置可能将 Helm 的配置文件和数据目录指向由仓库控制的位置。Helm 会在无需单独执行插件安装步骤的情况下，自动从 目录加载下载器插件，并在 仓库 URL 使用该插件协议时，于 进程中执行其程序。该命令以 repo-server 用户身份运行，能够读取仓库凭证及其他对进程可访

Vulnerability Title
Argo CD: A Kustomize Helm config home can run commands in the repo-server
Source: CVE Program / CVE List V5
Vulnerability Description
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From 2.1.0 until 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2, when an operator has enabled --enable-helm for kustomize build, helmGlobals.configHome can point Helm's config and data directories at a repository-controlled location. Helm automatically loads a downloader plugin from `<configHome>/.data/plugins` without a separate plugin-install step and executes its program inside argocd-repo-server when a helmCharts repository URL uses the plugin's protocol. The command runs as the repo-server user and can read repository credentials and other process-accessible data. An attacker can commit the Kustomization and plugin to a Git repository that an Application builds or upload the files through POST /api/v1/applications/manifestsWithFiles, also exposed by argocd app diff --local --server-side-generate. The upload path requires only Application get permission on an existing Application, without Application update or sync permission or repository write access. Both delivery paths require prior operator enablement of --enable-helm; deployments that do not enable it are not affected. Kustomize 4.1.0 first passed helmGlobals.configHome through to Helm. This issue is fixed in versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2.
