Gon gem lack of escaping certain input when outputting as JSON
🔗 CVE IDs covered (1)
📋 Description
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.
