{"id":"CVE-2026-55385","summary":"InvoiceShelf: SSRF via unvalidated Gotenberg PDF renderer host in PDF configuration","details":"InvoiceShelf is an open-source web & mobile app that helps track expenses, payments and create professional invoices and estimates. 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.","aliases":["GHSA-mfxg-qphw-3f3g"],"modified":"2026-10-16T02:48:01.445144449Z","published":"2026-10-14T19:25:32.410Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55385.json"},"references":[{"type":"WEB","url":"https://github.com/InvoiceShelf/InvoiceShelf/releases/tag/2.4.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55385.json"},{"type":"ADVISORY","url":"https://github.com/InvoiceShelf/InvoiceShelf/security/advisories/GHSA-mfxg-qphw-3f3g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55385"},{"type":"FIX","url":"https://github.com/InvoiceShelf/InvoiceShelf/commit/d615cfb4ff4841a3b8cda7fc850a2bb335521fe5"},{"type":"FIX","url":"https://github.com/InvoiceShelf/InvoiceShelf/pull/664"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/invoiceshelf/invoiceshelf","events":[{"introduced":"0"},{"fixed":"d615cfb4ff4841a3b8cda7fc850a2bb335521fe5"},{"fixed":"e3ab12ad773749668dc64e029d265a8440e21477"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.4.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["2.3.3","2.3.2","2.3.1","2.3.0","2.2.1","2.2.0","2.1.1","2.1.0","2.1.0-RC1","2.0.0","2.0.0-RC1","1.3.0","1.2.2","1.2.1","1.2.0","1.1.0","1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55385.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N"}]}
