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.
