Authorization Bypass in Manyfold ModelFilesController Prior to

Publication date: 2026-02-26

Assigner: GitHub, Inc.

Description
Manyfold is an open source, self-hosted web application for managing a collection of 3d models, particularly focused on 3d printing. Prior to version 0.133.1, the `get_model` method in `ModelFilesController` (line 158-160) loads models using `Model.find_param(params[:model_id])` without `policy_scope()`, bypassing Pundit authorization. All other controllers correctly use `policy_scope(Model).find_param()` (e.g., `ModelsController` line 263). Version 0.133.1 fixes the issue.

Executive Summary

The vulnerability exists in Manyfold, an open source web application for managing 3D models. Before version 0.133.1, the `get_model` method in the `ModelFilesController` loads models using `Model.find_param(params[:model_id])` without applying the `policy_scope()` authorization check provided by Pundit. This means that the method bypasses the intended access control, potentially allowing unauthorized access to models. Other controllers correctly use `policy_scope(Model).find_param()`, enforcing proper authorization. The issue was fixed in version 0.133.1.

Impact Analysis

This vulnerability can allow unauthorized users to access 3D models that they should not have permission to view or manage. Since the authorization check is bypassed in the affected method, sensitive or private models could be exposed to users without proper rights, potentially leading to information disclosure or misuse of intellectual property.

Mitigation Strategies

To mitigate this vulnerability, upgrade Manyfold to version 0.133.1 or later, where the issue with bypassing Pundit authorization in the get_model method is fixed.
