If you cannot patch yet, restrict payroll module permissions to trusted users only and monitor for suspicious activity related to payroll data access or creation.
Description
An authorization bypass vulnerability exists in the payroll module of Roskus Prospero Flow CRM versions before 5.15.10. Authenticated users with read payroll permission can view salary and banking details of employees from other companies within the same instance. Additionally, users with create payroll permission can create payroll records for employees of other companies. This occurs because the query listing is not properly scoped to the caller's company, and employee identifiers are validated only for global existence rather than company membership.
