Lifecycle Timeline
3Description
InvenTree is an Open Source Inventory Management System. From 1.2.3 to 1.2.6, the fix for CVE-2026-27629 upgraded the PART_NAME_FORMAT validator to use jinja2.sandbox.SandboxedEnvironment. However, the actual renderer in part/helpers.py was not updated and still uses the non-sandboxed jinja2.Environment. Additionally, the validator uses a dummy Part instance with pk=None, which allows conditional template expressions to behave differently during validation versus production rendering. A staff user with settings access can craft a template that passes validation but executes arbitrary code during rendering. This issue requires access by a user with granted staff permissions. This vulnerability is fixed in 1.2.7 and 1.3.0.
Analysis
Remote code execution in InvenTree 1.2.3 through 1.2.6 allows staff users with settings access to execute arbitrary code by crafting malicious Jinja2 templates that bypass sandbox validation. The vulnerability exists because the PART_NAME_FORMAT validator uses a sandboxed Jinja2 environment, but the actual rendering engine in part/helpers.py uses an unsandboxed environment, combined with a validation bypass via dummy Part instances with pk=None that behave differently during validation versus production execution. …
