Name of the Vulnerable Software and Affected Versions rails-html-sanitizer gem version 1.0.2 Ruby on Rails versions 4.2.x through 5.x

Description A cross-site scripting (XSS) issue allows remote attackers to inject arbitrary web script or HTML via an HTML entity that is mishandled by the Rails::Html::FullSanitizer class. This enables attackers to execute malicious scripts on the client-side.

Recommendations For rails-html-sanitizer gem version 1.0.2, update to a newer version to mitigate the risk. For Ruby on Rails versions 4.2.x through 5.x, ensure the rails-html-sanitizer gem is updated to a version that fixes the XSS vulnerability. As a temporary workaround, consider restricting the input allowed by the Rails::Html::FullSanitizer class to minimize the risk of exploitation.
