Background
buttle is an npm package that provides a rendering engine for processing markdown files. It is used to convert markdown files into HTML output. However, all versions of buttle are vulnerable to Cross-Site Scripting (XSS) attacks. The vulnerability arises from a misconfiguration in the rendering engine, which fails to properly sanitize the HTML output. This allows attackers to inject and execute arbitrary JavaScript code when processing malicious markdown files.

This can lead to various security risks, such as stealing sensitive user information, hijacking user sessions, or performing actions on behalf of the user without their consent. The vulnerability is rated as moderate in severity and is identified with the Common Weakness Enumeration (CWE) ID CWE-79.

Workaround
As there is no fix available, a possible workaround is to manually sanitize the HTML output generated by buttle. This can be done by using a separate library or function to sanitize the HTML code before rendering it in the browser. Here is an example of how to use the DOMPurify library to sanitize the HTML output:
const DOMPurify = require('dompurify');
const markdown = '...'; // Markdown content
const html = buttle.render(markdown);
const sanitizedHtml = DOMPurify.sanitize(html);
// Render sanitizedHtml in the browser
By using DOMPurify or a similar library, you can ensure that any potentially malicious JavaScript code is removed from the HTML output.
