Description

The remote Fedora 38 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2023-44daa9c1d4 advisory.

 - Redcarpet is a Ruby library for Markdown processing. In Redcarpet before version 3.5.1, there is an injection vulnerability which can enable a cross-site scripting attack.
