Overview
Affected versions of this package are vulnerable to Incorrect Authorization via the NodeRestriction admission controller process. An attacker can access unauthorized dynamic resources by creating mirror pods during pod creation when the DynamicResourceAllocation feature gate is enabled.
Note:
The DynamicResourceAllocation feature is disabled by default but it is recommended to check if it is enabled and to turn it off if not actively used.
To check if the feature is in use run the following commands:
kubectl get ResourceClaim --all-namespaceskubectl get pods --all-namespaces -o json | jq -r '.items[] | select(.metadata.annotations["kubernetes.io/config.mirror"] == "true") | "\(.metadata.namespace)/(.metadata.name)"'
