Description: yshop-crm through 2.1.3 contains a missing authorization vulnerability that allows any authenticated back-office user to approve or reject invoices via POST /admin-api/crm/invoice/check. The CrmInvoiceController check handler lacks @PreAuthorize and approver checks are commented out, letting attackers bypass the invoice approval workflow by supplying any invoice id.
