Pending upstream fix

Impact

The nokogiri vulnerability in nokogiri-1.18.10-java.gemspec is fixed in 1.19.3. However, nokogiri 1.19.3 requires Ruby >= 3.2, while logstash-9.0 ships JRuby 9.4 which provides Ruby 3.1.4 compatibility. Bundler refuses to install nokogiri 1.19.3 with this Ruby version. Resolution requires:

  1. Upstream to backport the security fix to the nokogiri 1.18.x line
  2. logstash-9.0 to be updated to ship JRuby 10.x — tracked by OS-1796 (de-vendor JRuby)
  3. A compatible version of nokogiri that maintains Ruby 3.1 support
