Summary
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->node) 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.
This vulnerability involves a use-after-free condition that can be triggered by processing specially crafted Extensible Stylesheet Language Transformations (XSLT). A remote attacker could exploit this to cause memory corruption, potentially leading to a denial of service or other impacts.
