En las versiones 8.0.0 a 10.0.0, el endpoint de uni\u00f3n de equipo (POST /multi-juicer/API/teams/{team}/join) aceptaba solicitudes con cualquier Content-Type, incluyendo text/plain. Debido a que ese tipo de contenido no activa un preflight de CORS, un atacante podr\u00eda alojar un formulario HTML de sitio cruzado que se auto-env\u00eda al endpoint y fuerza al navegador de una v\u00edctima a iniciar sesi\u00f3n como el equipo del atacante. Un atacante exitoso y no detectado puede hacer que las v\u00edctimas resuelvan sin saberlo los desaf\u00edos de Juice Shop bajo la identidad del equipo del atacante. En un contexto de CTF, esto permite al atacante inflar la puntuaci\u00f3n de su equipo utilizando la actividad de otros jugadores, y cualquier dato sensible que la v\u00edctima introduzca en \u2019su\u2019 Juice Shop termina en la instancia del atacante. La vulnerabilidad es explotable sin ninguna autenticaci\u00f3n previa; la v\u00edctima solo necesita visitar una p\u00e1gina que el atacante controla mientras tiene acceso de red al despliegue de MultiJuicer. SameSite=Strict en la cookie de sesi\u00f3n no mitiga esto, porque el ataque planta una nueva cookie en lugar de depender de una existente.
