Kubernetes secrets may store sensitive information such as passwords, tokens, and keys. Access to these secrets should be limited to a need-to-know basis via Kubernetes RBAC.
Check
Review the Kubernetes accounts and their corresponding roles.
If any accounts have read (list, watch, get) access to Secrets without a documented organizational requirement, this is a finding.
Run the below command to list the workload resources for applications deployed to Kubernetes: kubectl get all -A -o yaml
If Secrets are attached to applications without a documented requirement, this is a finding.
Fix
For Kubernetes accounts that have read access to Secrets without a documented requirement, modify the corresponding Role or ClusterRole to remove list, watch, and get privileges for Secrets.
