In the Loofah gem through 2.2.0 for Ruby, non-whitelisted HTML attributes may occur in sanitized output by republishing a crafted HTML fragment.
Loofah allows non-whitelisted attributes to be present in sanitized output when input with specially-crafted HTML fragments. Users are affected if running Loofah < 2.2.1, but only: * when running on MRI or RBX, * in combination with libxml2 >= 2.9.2. JRuby users are not affected.
