CVE-2026-13753 is a missing authorization vulnerability in the embedded web server of HP DeskJet 2800 Series printers running firmware version TBP1CN2612AR and earlier. Administrative setting pages in the normal web interface require administrator authentication before sensitive information is displayed, but multiple backend administrative API endpoints fail to enforce equivalent authorization checks. An unauthenticated attacker on the network can send crafted GET requests directly to those exposed endpoints and retrieve protected configuration data, including plaintext Wi‑Fi Direct credentials, device identity information, SNMP-related configuration, serial and service identifiers, and administrative security state details. The flaw is caused by improper access control on server-side administrative resources rather than a client-side UI issue.
