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。 Argo CD v2.10.3之前、v2.9.8之前和v2.8.12之前版本存在安全漏洞，该漏洞源于ArgoCD 的 helm 包中的 loadRepoIndex() 函数在获取数据时不限制大小或时间，可能导致内存不足使服务崩溃。

Vulnerability Title
Uncontrolled Resource Consumption vulnerability in ArgoCD's repo server
Source: CVE Program / CVE List V5
Vulnerability Description
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of ArgoCD starting from v2.4 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector. Specifically, it's possible to crash the repo server component through an out of memory error by pointing it to a malicious Helm registry. The loadRepoIndex() function in the ArgoCD's helm package, does not limit the size nor time while fetching the data. It fetches it and creates a byte slice from the retrieved data in one go. If the registry is implemented to push data continuously, the repo server will keep allocating memory until it runs out of it. A patch for this vulnerability has been released in v2.10.3, v2.9.8, and v2.8.12.
