{"schema":"threatline.record/2","record":{"id":"CVE-2026-55385","aliases":["GHSA-mfxg-qphw-3f3g"],"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.","categories":["Unclassified"],"product":"InvoiceShelf","vendor":"InvoiceShelf","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-55385","source_modified_at":"2026-10-20T02:02:13.638Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"InvoiceShelf","vendor":"InvoiceShelf","versions":[{"version":"< 2.4.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00454,"percentile":0.38424,"score_date":"2026-10-23"},"published_at":"2026-10-14T19:25:32.410Z","modified_at":"2026-10-20T02:02:13.638Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-55385","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-20T02:02:13.638Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-55385","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/InvoiceShelf/InvoiceShelf/security/advisories/GHSA-mfxg-qphw-3f3g","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/InvoiceShelf/InvoiceShelf/pull/664","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/InvoiceShelf/InvoiceShelf/commit/d615cfb4ff4841a3b8cda7fc850a2bb335521fe5","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/InvoiceShelf/InvoiceShelf/releases/tag/2.4.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-20T02:01:53.814292Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-20T02:02:13.638Z","content_hash":"08540fa3cd64494236de07b86c28d737d0cb9038f2f93ee3ab2e63546bd7e14c"}}
