High impact if exploited, but EPSS currently rates exploitation as unlikely (0.71%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
