Sanitize vulnerable to Cross-site Scripting via Improper neutralization of `noscript` element
Summary
Sanitize vulnerable to Cross-site Scripting via Improper neutralization of noscript element
Original description
The description as published by the source.
Sanitize is an allowlist-based HTML and CSS sanitizer. Versions 5.0.0 and later, prior to 6.0.1, are vulnerable to Cross-site Scripting. When Sanitize is configured with a custom allowlist that allows noscript elements, attackers are able to include arbitrary HTML, resulting in XSS (cross-site scripting) or other undesired behavior when that HTML is rendered in a browser. The default configurations do not allow noscript elements and are not vulnerable. This issue only affects users who are using a custom config that adds noscript to the element allowlist. This issue has been patched in version 6.0.1. Users who are unable to upgrade can prevent this issue by using one of Sanitize's default configs or by ensuring that their custom config does not include noscript in the element allowlist.
