Nokogiri: XML::Schema on JRuby allows network requests when NONET is set, bypassing CVE-2020-26247_CVE-2026-57234

{
    "lastseen": "",
    "description": "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.",
