CVE-2026-59236Network attack vector

Cross-tenant record injection via unchecked company identifier

Published Jul 15, 2026 · Updated Jul 15, 2026

Authorization bypass in Roskus Prospero Flow CRM before 5.14.0 allows remote authenticated users to inject records into other tenants. The CustomerImport, LeadImport, and ProductImport handlers map the spreadsheet's company_id value directly into new records without checking it against the authenticated user's company. Any signed-in role can submit a crafted spreadsheet to the Excel import endpoint, causing customer, lead, or product records to be created in a victim tenant.
