Title
yshop-crm through 2.1.3 Missing Authorization via CrmFlowController deleteFlowStep
Summary
yshop-crm through 2.1.3 fails to enforce authorization checks on the CrmFlowController deleteFlowStep endpoint, allowing any authenticated back-office user to delete arbitrary approval workflow steps. Attackers can invoke the DELETE /admin-api/crm/flow/delete-step endpoint without required permissions to remove approval steps that control contract, receivable, and invoice finalization processes.
