### Impact A vulnerability has been identified which enables [Standard users](https://ranchermanager.docs.rancher.com/how-to-guides/new-user-guides/authentication-permissions-and-global-configuration/manage-role-based-access-control-rbac/global-permissions) or above to elevate their permissions to Administrator in the `local` cluster. The `local` cluster means the cluster where Rancher is installed. It is named `local` inside the list of clusters in the Rancher UI. Standard users could leverage their existing permissions to manipulate Kubernetes secrets in the `local` cluster, resulting in the secret being deleted, but their read-level permissions to the secret being preserved. When this operation was followed-up by other specially crafted commands, it could result in the user gaining access to tokens belonging to service accounts in the `local` cluster. Users that have custom global roles which grant `create` and `delete` permissions on `secrets` would also be able to exploit this...

### Impact A vulnerability was identified in which users with update privileges on a namespace, can move that namespace into a project they don't have access to. After the namespace transfer is completed, their previous permissions are still preserved, which enables them to gain access to project-specific resources (such as [project secrets](https://ranchermanager.docs.rancher.com/how-to-guides/new-user-guides/kubernetes-resources-setup/secrets#creating-secrets-in-projects)). In addition, resources in the namespace will now count toward the [quota limit](https://ranchermanager.docs.rancher.com/how-to-guides/advanced-user-guides/manage-projects/manage-project-resource-quotas/about-project-resource-quotas) of the new project, potentially causing availability issues. User with roles `Project Owner` and `Project Member` on the source project can exploit this vulnerability; however, this would also apply to custom roles with similar privileges. The patched version include an improved RBA...
