The Shopify Application Security Team reported that ruby-loofah, a general library for manipulating and transforming HTML/XML documents and fragments, allows non-whitelisted attributes to be present in sanitized output when input with specially-crafted HTML fragments. This might allow to mount a code injection attack into a browser consuming sanitized output. For the stable distribution (stretch), this problem has been fixed in version 2.0.3-2+deb9u1. We recommend that you upgrade your ruby-loofah packages.
