### Impact This issue affects Rancher versions from 2.5.0 up to and including 2.5.16, from 2.6.0 up to and including 2.6.9 and 2.7.0. It was discovered that the security advisory CVE-2021-36782 (GHSA-g7j7-h4q8-8w2f), previously released by Rancher, missed addressing some sensitive fields, secret tokens, encryption keys, and SSH keys that were still being stored in plaintext directly on Kubernetes objects like `Clusters`. The exposed credentials are visible in Rancher to authenticated `Cluster Owners`, `Cluster Members`, `Project Owners` and `Project Members` of that cluster on the endpoints: - `/v1/management.cattle.io.cluster` - `/v1/management.cattle.io.clustertemplaterevisions` The remaining sensitive fields are now stripped from `Clusters` and other objects and moved to a `Secret` before the object is stored. The `Secret` is retrieved when the credential is needed. For objects that existed before this security fix, a one-time migration happens on startup. The fields that have ...

### Impact An issue was discovered in Rancher where an authorization logic flaw allows an authenticated user on any downstream cluster to (1) open a shell pod in the Rancher `local` cluster and (2) have limited `kubectl` access to it. The expected behavior is that a user does not have such access in the Rancher `local` cluster unless explicitly granted. This issue does not allow the user to escalate privileges in the `local` cluster directly (this would require another vulnerability to be exploited). The security issue happens in two different ways: 1. Shell pod access - This is when a user opens a shell pod in the Rancher UI to a downstream cluster that the user has permission to access. The web request can be intercepted using the browser's web inspector/network console or a proxy tool to change the shell's destination to the Rancher `local` cluster instead of the desired downstream cluster. - This flaw cannot be exploited to access a downstream cluster that the user has no p...

### Impact An issue was discovered in Rancher versions from 2.5.0 up to and including 2.5.16 and from 2.6.0 up to and including 2.6.9, where an authorization logic flaw allows privilege escalation via project role template binding (PRTB) and `-promoted` roles. This issue is not present in Rancher 2.7 releases. Note: Consult Rancher [documentation](https://ranchermanager.docs.rancher.com/how-to-guides/new-user-guides/authentication-permissions-and-global-configuration/manage-role-based-access-control-rbac/cluster-and-project-roles) for more information about cluster and project roles and [KB 000020097](https://www.suse.com/support/kb/doc/?id=000020097) for information about `-promoted` roles. This privilege escalation is possible for users with access to the `escalate` verb on PRTBs (`projectroletemplatebindings.management.cattle.io`), including users with `*` verbs on PRTBs (see notes below for more information). These users can escalate permissions for any `-promoted` resource (see...

### Impact An issue was discovered in Rancher versions up to and including 2.6.9 and 2.7.0, where the `cattle-token` secret, used by the `cattle-cluster-agent`, is predictable. Even after the token is regenerated, it will have the same value. This issue is not present in Rancher 2.5 releases. The `cattle-token` is used by Rancher's `cattle-cluster-agent` to connect to the Kubernetes API of Rancher provisioned downstream clusters. The problem occurs because the `cattle-token` secret does not use any random value in its composition, which causes it to always be regenerated with the same value. This can pose a serious problem if the token is compromised and needs to be recreated for security purposes. The usage of the `cattle-token` by an unauthorized user allows to escalate privileges to the cluster owner of the affected downstream cluster. It does not allow access to Rancher's own local cluster (the cluster where Rancher is provisioned). ### Workarounds In case it is not possible t...
