CVE-2026-35163

OctoPrint provides a web interface for controlling consumer 3D printers. Prior to 1.11.8 and 2.0.0rc3, Suppressed Command notification popups use PNotify rendering for printer-controlled payload.command and payload.message values in src/octoprint/static/js/app/viewmodels/terminal.js without HTML escaping. An attacker who convinces a victim to print a crafted file can inject HTML and JavaScript into the notification, disrupt prints, read information available to the victim including sensitive settings when permitted, or perform actions in the victim's OctoPrint session. This issue is fixed in versions 1.11.8 and 2.0.0rc3.

Summary		(es) OctoPrint proporciona una interfaz web para controlar impresoras 3D de consumo. Antes de las versiones 1.11.8 y 2.0.0rc3, las ventanas emergentes de notificación de Comando Suprimido utilizan el renderizado de PNotify para los valores payload.command y payload.message controlados por la impresora en src/octoprint/static/js/app/viewmodels/terminal.js sin escape HTML. Un atacante que convence a una víctima para imprimir un archivo manipulado puede inyectar HTML y JavaScript en la notificación, interrumpir impresiones, leer información disponible para la víctima, incluyendo configuraciones sensibles cuando esté permitido, o realizar acciones en la sesión de OctoPrint de la víctima. Este problema está solucionado en las versiones 1.11.8 y 2.0.0rc3.
