Summary

Improper Restriction of XML External Entity Reference (XXE) in Nokogiri on JRuby

Details

Severity

The Nokogiri maintainers have evaluated this as High Severity 7.5 (CVSS3.0) for JRuby users. (This security advisory does not apply to CRuby users.)

Impact

In Nokogiri v1.12.4 and earlier, on JRuby only, the SAX parser resolves external entities by default.

Users of Nokogiri on JRuby who parse untrusted documents using any of these classes are affected:

Nokogiri::XML::SAX::Parser
Nokogiri::HTML4::SAX::Parser or its alias Nokogiri::HTML::SAX::Parser
Nokogiri::XML::SAX::PushParser
Nokogiri::HTML4::SAX::PushParser or its alias Nokogiri::HTML::SAX::PushParser

Mitigation

JRuby users should upgrade to Nokogiri v1.12.5 or later. There are no workarounds available for v1.12.4 or earlier.

CRuby users are not affected.
