InvoiceShelf is an open-source web & mobile app that helps track expenses, payments and create professional invoices and estimates. Prior to version 2.2.0, a Server-Side Request Forgery (SSRF) vulnerability exists in the Invoice PDF generation module. User-supplied HTML in the invoice Notes field is passed unsanitised to the Dompdf rendering library, which will fetch any remote resources referenced in the markup.
