!!! warning "Potential XSS vulnerabilities"
    Showdown doesn't sanitize the input since Markdown relies on it to parse certain features correctly into HTML. As a result, this may lead to potential XSS injection vulnerabilities.

    Please refer to the [Markdown's XSS vulnerability](xss.md) page for more information.
