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's allowed tags in either of the following ways: allow both \"math\" and \"style\" elements,  or allow both \"svg\" and \"style\" 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 \"math\" or \"svg\" and \"style\" should either upgrade or use the following workaround immediately: Remove \"style\" from the overridden allowed tags, or remove \"math\" and \"svg\" from the overridden allowed tags.","rails-html-sanitizer is responsible for sanitizing HTML fragments in Rails applications.

The attacker could transfer private information, such as cookies that may include session information, from the victim's machine to the attacker. The attacker could send malicious requests to a web site on behalf of the victim, which could be especially dangerous to the site if the victim has administrator privileges to manage that site. Phishing attacks could be used to emulate trusted web sites and trick the victim into entering a password, allowing the attacker to compromise the victim's account on that web site. Finally, the script could exploit a vulnerability in the web browser itself possibly taking over the victim's machine, sometimes referred to as \"drive-by hacking.\"\nIn many cases, the attack can be launched without the victim even being aware of it. Even with careful users, attackers frequently use a variety of methods to encode the malicious portion of the attack, such as URL encoding or Unicode, so the request looks less suspicious.","Stable","Base","Simple",1,false,[],{"title":95,"metaDescription":96,"keywords":97,"canonicalUrl":98,"structuredData":99},"What is CVE-2022-23519?
