Original Description

Summary

Nokogiri v1.18.3 upgrades its dependency libxml2 to v2.13.6.

libxml2 v2.13.6 addresses:

CVE-2025-24928
- described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/847
CVE-2024-56171
- described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/828

Impact

CVE-2025-24928

Stack-buffer overflow is possible when reporting DTD validation errors if the input contains a long (~3kb) QName prefix.

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.

Affected versions

RubyGems

Package	Vulnerable	Fixed in
nokogiri	`< 1.18.3`	`1.18.3`

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

nokogiri RubyGems → `1.18.3`

bundler

bundle update nokogiri # Gemfile: gem "nokogiri", ">= 1.18.3"

Weakness

CWE-1395: Dependency on Vulnerable Third-Party Component

The product has a dependency on a third-party component that contains one or more known vulnerabilities.

How to prevent it

Requirements, Policy: In some industries such as healthcare [REF-1320] [REF-1322] or technologies such as the cloud [REF-1321], it might be unclear about who is responsible for applying patches for third-party vulnerabilities: the vendor, the operator/customer, or a separate service. Clarifying roles and responsibilities can be important to minimize confusion or unnecessary delay when third-party vulnerabilities are disclosed.
Requirements: Require a Bill of Materials for all components and sub-components of the product. For software, require a Software Bill of Materials (SBOM) [REF-1247] [REF-1311].
Architecture and Design, Implementation, Integration, Manufacturing: Maintain a Bill of Materials for all components and sub-components of the product. For software, maintain a Software Bill of Materials (SBOM). According to [REF-1247], "An SBOM is a formal, machine-readable inventory of software components and dependencies, information about those components, and their hierarchical relationships."
Operation, Patching and Maintenance: Actively monitor when a third-party component vendor announces vulnerability patches; fix the third-party component as soon as possible; and make it easy for operators/customers to obtain and apply the patch.
Operation, Patching and Maintenance: Continuously monitor changes in each of the product's components, especially when the changes indicate new vulnerabilities, end-of-life (EOL) plans, etc.
