GHSA-437m-7hj5-9mpw

Kruise allows leveraging the kruise-daemon pod to list all secrets in the entire cluster

Quick fix

GHSA-437m-7hj5-9mpw — github.com/openkruise/kruise: upgrade to the fixed version with the command below.

go get github.com/openkruise/kruise@v1.3.1

Details

### Impact 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.

### Workarounds For users that do not require imagepulljob functions, they can modify kruise-daemon-role to drop the cluster level secret get/list privilege
