CVE-2026-61744: InvenTree: Barcode-scan API (`POST /api/barcode/`) returns full serialized object data without enforcing the model's view role

• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days

Description

InvenTree is an Open Source Inventory Management System. Prior to 1.4.0, POST /api/barcode/ accepts an attacker-synthesized internal JSON barcode containing a lowercase model label and integer primary key, while BarcodeView uses IsAuthenticatedOrReadScope and requires only authentication or a general read scope. The built-in barcode plugin selects the object with model.objects.get(pk=...), and InvenTreeBarcodeMixin.format_matched_response() returns the complete model serializer output as instance without checking the caller's per-model view role. A low-privilege user can enumerate primary keys for parts, stock, locations, supplier and manufacturer parts, orders, and builds to disclose commercially sensitive inventory, pricing, supplier, customer, and order data. This issue is fixed in version 1.4.0.

Affected products

• InvenTree: before 1.4.0
