CVE-2026-87924Public exploitNetwork attack vector

Unauthenticated invoice generation via missing endpoint authentication

Published Sep 9, 2026 · Updated Sep 9, 2026

Missing authentication in Rizwan17 Inventory Management System allows remote attackers to generate invoices without signing in. The includes/invoice_bill.php endpoint processes attacker-supplied order_date and invoice_no parameters without checking for an authenticated session. Network access to the PHP endpoint is sufficient; the public request demonstrates unauthorized invoice generation, while the CNA reports only low integrity and availability impact.
