Risks

HELM is a powerful tool used for managing Kubernetes applications, enabling quick installation, updates, and deletion of applications. However, its unrestricted use can introduce significant risks:

Uncontrolled Application Deletion: Commands like helm delete $(helm list | head -n 2 | tail -n 1 | awk '{print $1}') can be used to delete applications listed by helm list. In combination with a simple loop, all applications could be deleted, leading to service disruptions and potential loss of critical services.

Sensitive Operations: HELM can deploy entire applications, making it crucial to control which images and configurations are used. Without proper oversight, unauthorized or insecure applications could be deployed, exposing the cluster to vulnerabilities.

To mitigate these risks, it is essential to implement strict permissions and restrictions on HELM usage.
