Cross-tenant payroll access via missing company scoping
Published Aug 14, 2026 · Updated Aug 14, 2026
Authorization bypass in Roskus Prospero Flow CRM before 5.15.10 allows remote authenticated users to read and create cross-tenant payroll records. PayrollIndexController builds its base listing query without a company constraint, while PayrollRequest accepts any globally existing user_id instead of checking company membership. The read payroll permission exposes salary, banking, payment, and note data from other tenants; create payroll permits fabricated entries attributed to their employees.
