yshop-crm through 2.1.3 fails to enforce authorization on the sendSms and sendMail endpoints in CrmCustomerController, allowing any authenticated back-office user to send SMS and email to arbitrary customers. Attackers can invoke POST /admin-api/crm/customer/send-sms and POST /admin-api/crm/customer/send-mail with arbitrary customerIds, templateCode, and templateParams to deliver unauthorized messages through the organization's SMS and email channels.
