CVE-2026-28225 Details
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.
A vulnerability in Manyfold versions prior to 0.133.1 allows authenticated contributors to bypass authorization checks in the ModelFilesController. The 'get_model' method fails to use 'policy_scope()', enabling unauthorized access to models and their associated files. This oversight affects all model_files endpoints and allows contributors to modify, delete, and unlawfully convert files from models they do not own.
Users can update to Manyfold version 0.133.1 to address this vulnerability.
