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 0.133.0, when model render generation is enabled, a logged-in user can achieve RCE by uploading a ZIP containing a file with a shell metacharacter in its name. The filename reaches a Ruby backtick call unsanitized. Version 0.133.0 fixes the issue.
