Attacker that has gain root privilege of the node that kruise-daemon run , can leverage the kruise-daemon pod to list all secrets in the entire cluster. After that, attackers can leverage the “captured” secrets (e.g. the kruise-manager service account token) to gain extra privilege such as pod modification.
For users that do not require imagepulljob functions, they can modify kruise-daemon-role to drop the cluster level secret get/list privilege
