CVE-2026-46336: MANYFOLD3D Manyfold

High severity, CVSS 7.1. EPSS: 0.5% chance of exploitation in the next 30 days.

Manyfold is an open source, self-hosted web application for managing a collection of 3d models, particularly focused on 3d printing. From 0.96.0 until 0.140.0, authenticated users can rename uploaded files with path traversal sequences because app/models/model_file.rb uses the user-controlled filename in File.join(model.path, filename) without sufficient sanitization, allowing files to be moved or written outside the configured library directory. This issue is fixed in version 0.140.0.

Affected products

• MANYFOLD3D Manyfold: from 0.96.0, before 0.140.0 (fixed in 0.140.0)
