{"id":"CVE-2025-71406","summary":"Nokogiri before 1.18.4 Use-After-Free via libxslt","details":"Nokogiri before 1.18.4 bundles a vulnerable version of libxslt (prior to 1.1.43) that contains two use-after-free vulnerabilities: CVE-2025-24855 (use-after-free of the XPath context node due to xsltEvalXPathStringNs leaking xpathCtxt-\u003enode) and CVE-2024-55549 (use-after-free related to excluded result prefixes/namespaces). Processing crafted XSLT can trigger memory corruption. Nokogiri 1.18.4 upgrades the bundled libxslt to 1.1.43 to resolve these issues.","aliases":["GHSA-mrxw-mxhj-p664"],"modified":"2026-08-28T11:31:01.324835974Z","published":"2026-08-25T15:15:58.585Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71406.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-416"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71406.json"},{"type":"ADVISORY","url":"https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-mrxw-mxhj-p664"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71406"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/nokogiri-before-use-after-free-via-libxslt"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sparklemotion/nokogiri","events":[{"introduced":"0"},{"fixed":"80edf1c35d79eae3a2fd7315f1fb61831ca3c94a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.18.4"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v1.18.3","v1.18.2","v1.18.1","v1.18.0","v1.18.0.rc1","v1.17.0","v1.16.0","v1.16.0.rc1","v1.15.2","v1.15.1","v1.15.0","v1.14.1","v1.14.0","v1.14.0.rc1","v1.13.0","v1.12.3","v1.12.2","v1.12.1","v1.12.0","v1.12.0.rc1","v1.11.3","v1.11.2","v1.11.1","v1.11.0","v1.11.0.rc4","v1.11.0.rc3","v1.11.0.rc2","v1.11.0.rc1","v1.10.3","v1.10.2","v1.8.5","v1.10.1","v1.10.0","v1.10.0.rc1","v1.9.1","v1.9.0","v1.9.0.rc1","v1.8.4","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.0.1","v1.7.0","v1.6.8","v1.6.8.rc3","v1.6.8.rc2","v1.6.8.rc1","v1.6.7.rc4","v1.6.6.2","v1.6.7.rc3","v1.6.7.rc2","v1.6.7.rc1","1.7.0.1-linux-binary1","v1.6.6.1","v1.6.6","v1.6.5","v1.6.4","v1.6.3.1","v1.6.3","v1.6.3.rc3","v1.6.3.rc2","v1.6.3.rc1","v1.6.2.1","v1.6.2","v1.6.2.rc3","v1.6.2.rc1","v1.6.2.beta.1","v1.6.0","v1.5.9","v1.6.0.rc1","v1.5.8","v1.5.7","v1.5.7.rc3","v1.5.7.rc2","v1.5.7.rc1","v1.5.6","v1.5.6.rc2","v1.5.5.rc2","v1.5.5.rc1","v1.5.4.rc3","v1.5.4.rc2","v1.5.4.rc1","v1.5.3","v1.5.3.rc6","v1.5.3.rc5","v1.5.3.rc4","v1.5.3.rc3","v1.5.3.rc1","v1.5.2","v1.5.1","v1.5.1.rc1","v1.5.0","v1.5.0.beta.3","v1.5.0.beta.4","REL_1.5.0.beta.2","REL_1.5.0.beta.1","REL_1.0.7","REL_1.0.6","REL_1.0.5","REL_1.0.4","REL_1.0.3","REL_1.0.2","REL_1.0.1","REL_1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71406.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
