Device setting changes via forged authenticated requests
Published Jul 7, 2026 · Updated Jul 7, 2026
Cross-site request forgery in Seiko Epson Web Config allows remote attackers to change device settings through an administrator's session. The embedded management interface processes a third-party page's state-changing request in the active session; Epson has not disclosed the affected handlers or request-validation failure. Exploitation requires an administrator to remain logged in and visit an attacker-controlled page, and the documented consequence is unauthorized configuration change only.
