How to fix?

Upgrade mini_magick to version 4.9.4 or higher.

Overview

mini_magick is a ruby wrapper for ImageMagick or GraphicsMagick command line.

Affected versions of this package are vulnerable to Remote Code Execution. A fetched remote image filename can cause remote command execution due to Image.open input being directly passed to Kernel#open, which accepts a | character followed by a command.
