InvenTree is an Open Source Inventory Management System. From 1.2.3 to 1.2.6, the fix for CVE-2026-27629 upgraded the PARTNAMEFORMAT 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.

InvenTree is an Open Source Inventory Management System. Prior to 1.2.7 and 1.3.0, a non-staff authenticated user can elevate their account to a staff level via a POST request against their user account endpoint. The write permissions on the API endpoint are improperly configured, allowing any user to change their staff status. This vulnerability is fixed in 1.2.7 and 1.3.0.

InvenTree is an Open Source Inventory Management System. From 0.16.0 to before 1.2.7, any authenticated InvenTree user can create a valid API token attributed to any other user in the system — including administrators and superusers — by supplying the target's user ID in the user field of a POST /api/user/tokens/ request. The returned token is immediately usable for full API authentication as the target user, from any network location, with no further interaction required. This vulnerability is fixed in 1.2.7 and 1.3.0.
