NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby-nokogiri package and not the ruby-nokogiri package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

Nokogiri is an open source XML and HTML library for the Ruby programming language. Prior to 1.19.4, the NONET parse option, which Nokogiri turns on by default for Nokogiri::XML::Schema (see CVE-2020-26247), was not correctly enforced on the JRuby implementation. As a result, a schema parsed with default options could still cause external resources to be fetched over the network, potentially enabling SSRF or XXE attacks. This vulnerability is fixed in 1.19.4.
