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. In affected versions no HTML escaping was being performed when processing quotes. This applies even when the
:escape_htmloption was being used. This is fixed in version 3.5.1 by the referenced commit. - References
