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_html option was being used. This is fixed in version 3.5.1 by the
referenced commit.
