CVSS v3.x: 6.1 (Medium)
- >= 1.0.4
There is a possible XSS vulnerability in rails-html-sanitizer. The gem allows non-whitelisted attributes to be present in sanitized output when input with specially-crafted HTML fragments, and these attributes can lead to an XSS attack on target applications.
This issue is similar to CVE-2018-8048 in Loofah.
