  "description": "rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications. Prior to version 1.4.4, a possible XSS vulnerability with certain configurations of Rails::Html::Sanitizer may allow an attacker to inject content if the application developer has overridden the sanitizer\u0027s allowed tags in either of the following ways: allow both \u0022math\u0022 and \u0022style\u0022 elements,  or allow both \u0022svg\u0022 and \u0022style\u0022 elements. Code is only impacted if allowed tags are being overridden. . This issue is fixed in version 1.4.4. All users overriding the allowed tags to include \u0022math\u0022 or \u0022svg\u0022 and \u0022style\u0022 should either upgrade or use the following workaround immediately: Remove \u0022style\u0022 from the overridden allowed tags, or remove \u0022math\u0022 and \u0022svg\u0022 from the overridden allowed tags.",
