Hi,

The following vulnerability was published for ruby-gon.

CVE-2020-25739[0]:
| An issue was discovered in the gon gem before gon-6.4.0 for Ruby.
| MultiJson does not honor the escape_mode parameter to escape fields as
| an XSS protection mechanism. To mitigate, json_dumper.rb in gon now
| does escaping for XSS by default without relying on MultiJson.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
