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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:N","score":2.6},"cwes":["CWE-178","CWE-184","CWE-611"],"references":["https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-8678-w3jw-xfc2"],"products":["nokogiri:nokogiri"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-57234","score":0.00198,"percentile":0.09544,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-8678-w3jw-xfc2","url":"https://osv.dev/vulnerability/GHSA-8678-w3jw-xfc2","summary":"Nokogiri: XML::Schema on JRuby allows network requests when NONET is set, bypassing CVE-2020-26247","modified":"2026-09-10T03:51:08.233410080Z","packages":[{"ecosystem":"RubyGems","name":"nokogiri","purl":"pkg:gem/nokogiri","ranges":["<1.19.4"],"fixed":["1.19.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
