The mutation performs no authentication or authorization checks before creating a customer portal session linked to any tenant Stripe account. An attacker can access and manage subscription data for any tenant without credentials."

La mutación no realiza comprobaciones de autenticación ni de autorización antes de crear una sesión del portal del cliente vinculada a cualquier cuenta de Stripe de inquilino. Un atacante puede acceder y gestionar datos de suscripción para cualquier inquilino sin credenciales."
