The Shopify Application Security Team discovered that ruby-sanitize, a whitelist-based HTML sanitizer, is prone to a HTML injection vulnerability. A specially crafted HTML fragment can cause to allow non- whitelisted attributes to be used on a whitelisted HTML element.

For the stable distribution (stretch), this problem has been fixed in version 2.1.0-2+deb9u1.

We recommend that you upgrade your ruby-sanitize packages.
