| Doc Text: |
A flaw was found in the `sanitize-html` library. Under its default configuration, an attacker can embed malicious content within a disallowed `xmp` element. This vulnerability allows the attacker to bypass the HTML sanitization process, leading to stored Cross-Site Scripting (XSS). Successful exploitation can result in arbitrary code execution or information disclosure when a user views the affected content.
