Users with `create` but not `override` privileges can perform local sync in argo-cd

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. "Local sync" is an Argo CD feature that allows developers to temporarily override an Application's manifests with locally-defined manifests. Use of the feature should generally be limited to highly-trusted users, since it allows the user to bypass any merge protections in git. An improper validation bug allows users who have `create` privileges but not `override` privileges to sync local manifests on app creation. All other restrictions, including AppProject restrictions are still enforced. The only restriction which is not enforced is that the manifests come from some approved git/Helm/OCI source. The bug was introduced in 1.2.0-rc1 when the local manifest sync feature was added. The bug has been patched in Argo CD versions 2.10.3, 2.9.8, and 2.8.12. Users are advised to upgrade. Users unable to upgrade may mitigate the risk of branch protection bypass by removing `applications, create` RBAC access. The only way to eliminate the issue without removing RBAC access is to upgrade to a patched version.

特权管理不恰当

ArgoCD 安全漏洞

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 存在安全漏洞，该漏洞源于允许具有create权限但没有override权限的用户执行Local sync功能。
