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. Ubuntu-Description: It was discovered that Gon gem did not properly escape certain input. An attacker could use this vulnerability to execute a cross-site scripting (XSS) attack.
