{"id":"CVE-2026-55385","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-55385","generatedAt":"2026-10-28T01:48:25.414Z","title":"InvoiceShelf is an open-source web & mobile app that helps track expenses, payments and create professional invoices and estimates.","description":"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.","published":"2026-10-14T20:17:49.000Z","lastModified":"2026-10-20T03:17:15.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N"},"cwe":["CWE-918"],"affected":[],"epss":{"score":0.00576,"percentile":0.47238,"date":"2026-10-26","history":[{"date":"2026-10-15","score":0.00454,"percentile":0.37876}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.58%).
