Summary
Nokogiri's CRuby extension fails to check the return value from
xmlC14NExecutein the methodNokogiri::XML::Document#canonicalizeandNokogiri::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
RuntimeErroron 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).
