Original Advisory
All versions of html-pdf-chrome are vulnerable to Server-Side Request Forgery (SSRF). The package executes HTTP requests if the parsed HTML contains external references to resources, such as <iframe src="http://localhost" height="800px" width="800px"></iframe>. This allows attackers to access resources through HTTP that are accessible to the server, including private resources in the hosting environment.
