Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling. An attacker can crash the controller process by sending an oversized POST request to the admission webhook, which exhausts memory because the handler decodes the request body without a size limit. The attacker must be able to reach the webhook port from the pod network, and the severity for each consumer of the handler depends on its failurePolicy setting.
