Summary
Frappe Framework 15.x before 15.107.3 and 16.x before 16.17.0 relies on a vulnerable pdfkit library for PDF generation. Crafted content passed to PDF rendering can make the server fetch internal resources or embed local server files in generated PDFs, which is a server-side request forgery (CWE-918). An authenticated user with low privileges can trigger this without user interaction.
