CVE-2026-46336 Details
Description
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.
A path traversal vulnerability has been identified in Manyfold versions 0.96.0 prior to 0.140.0. This issue allows authenticated users to rename uploaded files using traversal sequences, which can manipulate file locations outside the designated library directory. The vulnerability arises because the application does not adequately sanitize user-controlled filenames before using them in file paths. As a result, files can be moved or written to unintended locations, potentially leading to unauthorized access or modification of files on the server.
Users can upgrade to Manyfold version 0.140.0 or later, where this vulnerability has been fixed.
