SUSE Rancher: Privilege Escalation Through Kubernetes Secret Manipulation
Description

An Improper Privilege Management vulnerability in SUSE Rancher allowed standard users to 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. This issue affects Rancher: from >= 2.6.0 before < 2.6.13, from >= 2.7.0 before < 2.7.4.
