Ruby/nokogiri/1.16.0
Nokogiri (鋸) makes it easy and painless to work with XML and HTML from Ruby. It provides a sensible, easy-to-understand API for reading, writing, modifying, and querying documents. It is fast and standards-compliant by relying on native parsers like libxml2, libgumbo, or xerces.

CVE-2024-56171 Use-after-free is possible during validation against untrusted XML Schemas (.xsd) and, potentially, validation of untrusted documents against trusted Schemas if they make use of xsd:keyref in combination with recursively defined types that have additional identity constraints.

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-xc9x-jj77-9p9j. This link is maintained to preserve external references.
Original Description Summary Nokogiri upgrades its dependency libxml2 as follows: - v1.15.6 upgrades libxml2 to 2.11.7 from 2.11.6 - v1.16.2 upgrades libxml2 to 2.12.5 from 2.12.4
libxml2 v2.11.7 and v2.12.5 address the following vulnerability:
CVE-2024-25062 / https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-25062 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/604 - patched by https://gitlab.gnome.org/GNOME/libxml2/-/commit/92721970
Please note that this advisory only applies to the CRuby implementation of Nokogiri, and only if the packaged libraries are being used. If you've overridden defaults at installation time to use system libraries instead of packaged libraries, you should instead pay attention to your distro's libxml2 release announcements.
JRuby users are not affected.
Severity The Nokogiri maintainers have evaluated this as Moderate .
Impact From the CVE description, this issue applies to the xmlTextReader module (which underlies Nokogiri::XML::Reader):
When using the XML Reader interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to an xmlValidatePopElement use-after-free.
Mitigation Upgrade to Nokogiri ~> 1.15.6 or >= 1.16.2.
Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile and link Nokogiri against patched external libxml2 libraries which will also address these same issues.

Secure versions: [1.19.1]
Recommendation: Update to version 1.19.1.
Published date: 2026-02-18T21:57:38Z
Summary Nokogiri's CRuby extension fails to check the return value from xmlC14NExecute in the method Nokogiri::XML::Document#canonicalize and Nokogiri::XML::Node#canonicalize. When canonicalization fails, an empty string is returned instead of raising an exception. This incorrect return value may allow downstream libraries to accept invalid or incomplete canonicalized XML, which has been demonstrated to enable signature validation bypass in SAML libraries.
JRuby is not affected, as the Java implementation correctly raises RuntimeError on canonicalization failure.
Mitigation Upgrade to Nokogiri >= 1.19.1.
Severity The maintainers have assessed this as Medium severity. Nokogiri itself is a parsing library without a clear security boundary related to canonicalization, so the direct impact is that a method returns incorrect data on invalid input. However, this behavior was exploited in practice to bypass SAML signature validation in downstream libraries (see References).
Credit This vulnerability was responsibly reported by HackerOne researcher d4d.

Summary Nokogiri v1.18.9 patches the vendored libxml2 to address CVE-2025-6021, CVE-2025-6170, CVE-2025-49794, CVE-2025-49795, and CVE-2025-49796.
Impact and severity CVE-2025-6021 A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.

CVE-2025-6170 A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.

Summary Nokogiri v1.18.8 upgrades its dependency libxml2 to v2.13.8 .
libxml2 v2.13.8 addresses:
CVE-2025-32414 CVE-2025-32415 Impact CVE-2025-32414: No impact In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and xmlPythonFileReadRaw because of a difference between bytes and characters.
There is no impact from this CVE for Nokogiri users.
CVE-2025-32415: Low impact In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema with certain identity constraints, or a crafted XML schema must be used.
In the upstream issue, further context is provided by the maintainer:
The bug affects validation against untrusted XML Schemas (.xsd) and validation of untrusted documents against trusted Schemas if they make use of xsd:keyref in combination with recursively defined types that have additional identity constraints.
MITRE has published a severity score of 2.9 LOW (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L) for this CVE.

Secure versions: [1.19.1]
Recommendation: Update to version 1.19.1.
Published date: 2024-02-04
Summary Nokogiri upgrades its dependency libxml2 as follows: - v1.15.6 upgrades libxml2 to 2.11.7 from 2.11.6 - v1.16.2 upgrades libxml2 to 2.12.5 from 2.12.4
libxml2 v2.11.7 and v2.12.5 address the following vulnerability:
CVE-2024-25062 / https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-25062 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/604 - patched by https://gitlab.gnome.org/GNOME/libxml2/-/commit/92721970
Please note that this advisory only applies to the CRuby implementation of Nokogiri, and only if the packaged libraries are being used. If you've overridden defaults at installation time to use system libraries instead of packaged libraries, you should instead pay attention to your distro's libxml2 release announcements.
JRuby users are not affected.
Severity The Nokogiri maintainers have evaluated this as Moderate .
Impact From the CVE description, this issue applies to the xmlTextReader module (which underlies Nokogiri::XML::Reader):
When using the XML Reader interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to an xmlValidatePopElement use-after-free.
Mitigation Upgrade to Nokogiri ~> 1.15.6 or >= 1.16.2.
Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile and link Nokogiri against patched external libxml2 libraries which will also address these same issues.
