However, the vendor considered this a vulnerability and released a security patch.\n\nThis issue was fixed in version 1.3.4."

La aplicación procesa de forma insegura el parámetro en el lado del cliente, permitiendo a un atacante ejecutar JavaScript arbitrario en el contexto del navegador de la víctima.\nUn atacante con la capacidad de establecer una cookie puede realizar un ataque más grave, por lo que evaluamos el impacto y el riesgo de explotación como mínimos. Sin embargo, el proveedor consideró esto una vulnerabilidad y lanzó un parche de seguridad.\n\nEste problema se solucionó en la versión 1.3.4."
