CVE-2024-45041 Information

Description

External Secrets Operator is a Kubernetes operator that integrates external secret management systems. The external-secrets has a deployment called default-external-secrets-cert-controller which is bound with a same-name ClusterRole. This ClusterRole has \get/list\ verbs of secrets resources. It also has path/update verb of validatingwebhookconfigurations resources.

This vulnerability is fixed in 0.10.2.
