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.

For Debian 8 jessie, these problems have been fixed in version 3.1.2-1+deb8u1.
