How to Fix GHSA-5w6v-399v-w3cc

To remediate this vulnerability, upgrade all affected Nokogiri dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

nokogiri fixed: 1.18.8 
Upgrade nokogiri to 1.18.8
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

How to Check if You Are Affected

To determine whether your application is affected by GHSA-5w6v-399v-w3cc, inspect your project dependencies for Nokogiri:

inspect dependencies for nokogiri

Analyze the terminal output to locate any version of Nokogiri in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.18.8), your application is affected.

In Nokogiri, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Summary Nokogiri v1.18.8 upgrades its dependency libxml2 to [v2.13.8](https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.13.8). libxml2 v2.13.8 addresses: - CVE-2025-32414 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/889 - CVE-2025-32415 - described at https://gitlab.gnome.org/GNOME/libxml2/-/issues/890 ## 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.
