npm install @marp-team/marp-core@3.9.1npm install @marp-team/marp-core@4.0.1Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @marp-team/marp-coreHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2024-56510, inspect your project dependencies using npm:
npm ls @marp-team/marp-coreAnalyze the terminal output to locate any version of @marp team/marp core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.9.1), your application is affected.
Note: The npm ls @marp-team/marp-core command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

"details" : "Marp Core ([`@marp-team/marp-core`](https://www.npmjs.com/package/@marp-team/marp-core)) from v3.0.2 to v3.9.0 and v4.0.0, are vulnerable to cross-site scripting (XSS) due to improper neutralization of HTML sanitization.\n\n### Impact\n\nMarp Core includes an HTML sanitizer with allowlist support. In the affected versions, the built-in allowlist is enabled by default. When the allowlist is active, if insufficient HTML comments are included, the sanitizer may fail to properly sanitize HTML content and lead cross-site scripting (XSS).\n\n### Patches\n\nMarp Core [v3.9.1](https://github.com/marp-team/marp-core/releases/tag/v3.9.1) and [v4.0.1](https://github.com/marp-team/marp-core/releases/tag/v4.0.1) have been patched to fix that.\n\n### Workarounds\n\nIf you are unable to update the package immediately, disable all HTML tags by setting `html: false` option in the `Marp` class constructor.\n\n```javascript\nconst marp = new Marp({ html: false })\n```\n\n### References\n\n- [CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')](https://cwe.mitre.org/data/definitions/79.html)\n- https://github.com/marp-team/marp-core/pull/282\n- https://github.com/marp-team/marp-core/commit/61a1def244d1b6faa8e2c0be97ec0b68cab3ab49\n\n### Credits\n\nThanks to @Ry0taK for finding out this vulnerability.",
