Description

InvenTree is an Open Source Inventory Management System. 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.

Affected products

How to fix

Upgrade to a fixed version: InvenTree 1.2.6. Check the vendor advisory for mitigations.
