CVE-2026-63563 affects certain Sharp and Toshiba Tec multifunction printers shipped for a specific market with the user authentication feature disabled in the initial configuration. When operated in that default state, unauthenticated users can access address book editing functionality and multiple features related to Document Filing. The issue is a security misconfiguration in the shipped default setup rather than a memory corruption or code execution flaw. Products intended for the Japanese market are not affected.
