What is CVE-2026-28225?

CVE-2026-28225 is a medium-severity missing authorization vulnerability in manyfold3d manyfold, published on 26 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official 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.
