CVE-2026-46336
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedManyfold 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped0.140.0
- Backup your database and any existing data
- Check the Manyfold release notes for version 0.140.0 for any specific upgrade instructions
- If using Docker, update your container to pull version 0.140.0
- If using a gem-based installation, update the Manyfold gem to version 0.140.0 (e.g., bundle update manyfold or gem install manyfold -v 0.140.0)
- Review any new configuration requirements in version 0.140.0
- Restart the application services
- Verify the application is running correctly and test file upload/rename functionality
