Overview
Affected versions of this package are vulnerable to Incorrect Authorization via the HandleSection function. An attacker can gain unauthorized cluster-level privileges, access sensitive data across tenants, and disrupt cluster operations by submitting specially crafted resources that exploit the controller's elevated permissions and lack of resource scope validation. This is only exploitable if the controller is running with cluster-admin privileges and the attacker has Tenant Owner permissions.
