Argo CD's certificate verification is skipped for connections to OIDC providers

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD starting with version 0.4.0 and prior to 2.2.11, 2.3.6, and 2.4.5 is vulnerable to an improper certificate validation bug which could cause Argo CD to trust a malicious (or otherwise untrustworthy) OpenID Connect (OIDC) provider. A patch for this vulnerability has been released in Argo CD versions 2.4.5, 2.3.6, and 2.2.11. There are no complete workarounds, but a partial workaround is available. Those who use an external OIDC provider (not the bundled Dex instance), can mitigate the issue by setting the `oidc.config.rootCA` field in the `argocd-cm` ConfigMap. This mitigation only forces certificate validation when the API server handles login flows. It does not force certificate verification when verifying tokens on API calls.

证书验证不恰当

ArgoCD 信任管理问题漏洞

ArgoCD是一个应用软件。用于Kubernetes的声明性GitOps连续交付工具。它持续监控正在运行的应用程序并将当前的实时状态与所需的目标状态（例如 Git 仓库中的配置）进行比较，在 Git 仓库更改时自动同步和部署应用程序。 ArgoCD 0.4.0到2.2.11版本、 2.3.6到 2.4.5版本存在安全漏洞，该漏洞源于容易受到不正确的证书验证错误的影响，这可能导致 Argo CD 信任恶意（或其他不可信的）OpenID Connect (OIDC) 提供者。
