  "summary" : "External Secrets Operator vulnerable to privilege escalation",
  "details" : "### Details\nThe 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(https://github.com/external-secrets/external-secrets/blob/main/deploy/charts/external-secrets/templates/cert-controller-rbac.yaml#L49). It also has path/update verb of validatingwebhookconfigurations resources(https://github.com/external-secrets/external-secrets/blob/main/deploy/charts/external-secrets/templates/cert-controller-rbac.yaml#L27). As a result, if a malicious user can access the worker node which has this deployment. he/she can:\n1. For the \"get/list secrets\" permission, he/she can abuse the SA token of this deployment to retrieve or get ALL secrets in the whole cluster, including the cluster-admin secret if created. After that, he/she can abuse the cluster-admin secret to do whatever he/she likes to the whole cluster, resulting in a cluster-level privilege escalation.\n\n2. For the patch/update verb of validatingwebhookconfigurations, the malicious user can abuse these permissions to get sensitive data or lanuch DoS attacks:\n\nFor the privilege escalation attack, by updating/patching a Webhook to make it listen to Secret update operations, the attacker can capture and log all data from requests attempting to update Secrets. More specifically, when a Secret is updated, this Webhook sends the request data to the logging-service, which can then log the content of the Secret. This way, an attacker could indirectly gain access to the full contents of the Secret.\n\nFor the DoS attack, by updating/patching a Webhook, and making it deny all Pod create and update requests, the attacker can prevent any new Pods from being created or existing Pods from being updated, resulting in a Denial of Service (DoS) attack.\n\n### PoC\nPlease see the \"Details\" section\n\n### Impact\nPrivilege escalation",
