Prior to version 2.4.0, InvoiceShelf's PDFConfigurationRequest.php validates the owner-controlled gotenberg_host setting only as a syntactically valid URL. GotenbergPDFDriver::loadView later sends a multipart HTTP request containing rendered invoice, estimate, or payment HTML as document.html to that host without rejecting private, loopback, link-local, or reserved addresses. An owner can use PDF generation to reach internal services or cloud metadata endpoints, and a configured external host receives customer names, addresses, line items, totals, and company identifiers from subsequent PDF renders. This issue is fixed in version 2.4.0.","state":0,"publishedAt":"2026-10-14T19:25:32.41+00:00","modifiedAt":"2026-10-20T02:02:13.638+00:00","affected":[{"ecosystem":"Vendor product","name":"InvoiceShelf","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"InvoiceShelf\",\n                    \"product\": \"InvoiceShelf\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.4.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N","score":6.8,"severity":"MEDIUM"}],"references":["https://github.com/InvoiceShelf/InvoiceShelf/security/advisories/GHSA-mfxg-qphw-3f3g","https://github.com/InvoiceShelf/InvoiceShelf/pull/664","https://github.com/InvoiceShelf/InvoiceShelf/commit/d615cfb4ff4841a3b8cda7fc850a2bb335521fe5","https://github.com/InvoiceShelf/InvoiceShelf/releases/tag/2.4.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55385","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55385","identifiers":["CVE-2026-55385"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
