Argo Workflows Chart: Excessive Privileges in Workflow Role

Argo Workflows Chart is used to set up argo and its needed dependencies through one command. Prior to 0.44.0, the workflow-role has excessive privileges, the worst being create pods/exec, which will allow kubectl exec into any Pod in the same namespace, i.e. arbitrary code execution within those Pods. If a user can be made to run a malicious template, their whole namespace can be compromised. This affects versions of the argo-workflows Chart that use appVersion: 3.4 and above, which no longer need these permissions for the only available Executor, Emissary. It could also affect users below 3.4 depending on their choice of Executor in those versions. This only affects the Helm Chart and not the upstream manifests. This vulnerability is fixed in 0.44.0.

带着不必要的权限执行

Argo Workflows 安全漏洞

Argo Workflows是Argo项目的一个用于 Kubernetes 的开源容器原生工作流引擎。 Argo Workflows 0.44.0之前版本存在安全漏洞，该漏洞源于workflow-role具备过度的权限，从而导致可在Pod内执行任意代码。
