Authorization Bypass Through User-Controlled Key (CWE-639) in the Excel import handlers (CustomerImport, LeadImport, ProductImport) in Roskus Prospero Flow CRM before 5.14.0 allows a remote, authenticated user of any role or company to create customer, lead, and product records inside another company's tenant via a spreadsheet whose company_id column points to the victim tenant, uploaded to POST /customer/import/excel/save, which maps company_id directly from the file and performs no check that it matches the authenticated user's company.
