GitHub Vulnerability Alerts

GHSA-wx95-c6cv-8532

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).

Code Review

This pull request updates the nokogiri dependency in Gemfile.lock from version 1.18.9 to 1.19.2 to address a security vulnerability. Feedback suggests correcting the PR metadata to match the version used and updating the Gemfile constraint to ~> 1.19 to prevent future downgrades to vulnerable versions.

[gemini-code-assist]

The Gemfile.lock has been updated to version 1.19.2, which addresses the security vulnerability (GHSA-wx95-c6cv-8532). However, there are two points of concern:

1. PR Metadata Mismatch: The PR title and description specify version 1.19.1. While 1.19.2 is a valid patch release containing the fix, the PR metadata should be updated for accuracy.
2. Dependency Constraint: The DEPENDENCIES section (line 812) still shows nokogiri (~> 1.18), indicating that the Gemfile itself was not updated. To prevent the accidental reintroduction of vulnerable versions (like 1.18.9) in future dependency resolutions, the Gemfile should be updated to require nokogiri version 1.19.1 or higher (e.g., ~> 1.19).
