Multiple vulnerabilities were discovered in Loofah, a Ruby library for HTML/XML transformation and sanitization. An attacker could launch cross-site scripting (XSS) and denial-of-service (DoS) attacks through crafted HTML/XML documents.
For Debian 10 buster, these problems have been fixed in version 2.2.3-1+deb10u2.
We recommend that you upgrade your ruby-loofah packages.
