CVE-2020-25739 (GCVE-0-2020-25739)

Vulnerability from cvelistv5 – Published: 2020-09-23 13:53 – Updated: 2024-08-04 15:40

Summary

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.

Severity

No CVSS data available.
