CVE-2020-25739

6.1 mediumEPSS 1.4%

Medium (6.1). EPSS 1.4% chance of exploitation in the next 30 days. Fixed in gon 6.4.0.

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.
