CVE-2026-43925

FOSSBilling is a free, open-source billing and client management system. Prior to version 0.8.0, an unauthenticated mass assignment vulnerability in the client self-registration endpoint allows any visitor to assign themselves to an arbitrary client group during sign-up. Because client groups can gate promo code eligibility, an attacker may apply group-restricted discount codes and receive unauthorized discounts. Version 0.8.0 contains a patch. As a workaround, administrators can either remove group restrictions from promo codes or disable client self-registration (Settings → Clients → Disable signup).

Summary		(es) FOSSBilling es un sistema de facturación y gestión de clientes gratuito y de código abierto. Antes de la versión 0.8.0, una vulnerabilidad de asignación masiva no autenticada en el endpoint de auto-registro de clientes permite a cualquier visitante asignarse a un grupo de clientes arbitrario durante el registro. Debido a que los grupos de clientes pueden restringir la elegibilidad de códigos promocionales, un atacante puede aplicar códigos de descuento restringidos por grupo y recibir descuentos no autorizados. La versión 0.8.0 contiene un parche. Como solución alternativa, los administradores pueden eliminar las restricciones de grupo de los códigos promocionales o deshabilitar el auto-registro de clientes (Ajustes ? Clientes ? Deshabilitar registro).
