CVE-2020-25739
MultiJson does not honor the escape_mode parameter to escape fields as an XSS protection mechanism.
MEDIUM 6.1EPSS 1.38%
Does this matter?
Lower severity and a low EPSS score (1.38%). Track it; it rarely justifies an emergency change on its own.
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.
