This is a highly critical issue, I've described two ways to exploit this on a fully updated Fedora 38 to execute arbitrary commands here: https://bugzilla.redhat.com/show_bug.cgi?id=2241108#c3

Proposed as a Blocker for 39-final by Fedora user thebeanogamer using the blocker tracking app because: The release must contain no known security bugs of 'important' or higher impact according to the Red Hat severity classification scale which cannot be satisfactorily resolved by a package update (e.g. issues during installation). This impacts Libreoffice and ImageMagick, which can run in a live environment before package updates.
