As published by the source; long descriptions are shortened.

Summary Nokogiri v1.14.3 upgrades the packaged version of its dependency libxml2 to v2.10.4 from v2.10.3. libxml2 v2.10.4 addresses the following known vulnerabilities: - CVE-2023-29469: Hashing of empty dict strings isn't deterministic - CVE-2023-28484: Fix null deref in xmlSchemaFixupComplexType - Schemas: Fix null-pointer-deref in xmlSchemaCheckCOSSTDerivedOK Please note that this advisory only applies to the CRuby implementation of Nokogiri < 1.14.3, 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. Mitigation Upgrade to Nokogiri = 1.14.3. Users who are unable to upgrade Nokogiri may also choose a more complicated mitigation: compile and link Nokogiri against external libraries libxml2 = 2.10.4 which will also address these same issues. Impact No public information has yet been published about…

# Patch Next advisory brief: GHSA-pxvg-2qj5-37jq

Advisory: Nokogiri updates packaged libxml2 to v2.10.4 to resolve multiple CVEs
IDs: GHSA-pxvg-2qj5-37jq
Record: https://patchnext.com/advisories/ghsa-pxvg-2qj5-37jq (revision 1, source checked 26 Oct 2026, 15:44 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: nokogiri 1.14.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- RubyGems nokogiri: affected < 1.14.3; fixed in 1.14.3

## Suggested inspection (read-only)
- RubyGems nokogiri: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on nokogiri.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
