Overview
pontedilana/php-weasyprint is a PHP library allowing PDF generation from an url or a html page.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) and local file disclosure in the isOptionUrl() and handleArrayOptions() methods of src/Pdf.php, which validate the attachment option with FILTER_VALIDATE_URL and then fetch it via file_get_contents() without restricting the scheme. A user who can influence the attachment value can read internal HTTP endpoints, cloud metadata, or local files into the generated PDF by supplying a URL with a scheme such as file://, ftp://, or php://filter/convert.base64-encode/resource=/etc/passwd, all of which pass validation and are fetched as content. Exploitation requires control over the attachment option through request parameters, tenant configuration, or user-controllable fields, and disclosed content is returned only by being embedded in the output PDF.
