Summary
The cluster-samples-operator in Red Hat OpenShift Container Platform grants its role coreos-pull-secret-reader read access to all Secret resources in the openshift-config namespace, although the operator needs only the pull-secret Secret. This is execution with unnecessary privileges (CWE-250). An adjacent attacker with low privileges who compromises the samples-operator pod or its service account token through a separate vulnerability can read secrets such as OAuth identity provider and cloud provider credentials.

Description from the CNA
A flaw was found in the cluster-samples-operator. The RBAC Role coreos-pull-secret-reader in namespace openshift-config grants get, list, and watch permissions on all Secret resources without resourceNames scoping. The operator only requires access to the pull-secret Secret. If the samples-operator pod or its service account token is compromised through a separate vulnerability, an attacker could read all secrets in openshift-config, potentially including OAuth identity provider credentials, cloud provider credentials, and other sensitive cluster configuration.
