      "value": "WLED's GET /json/cfg endpoint (registered in wled00/wled_server.cpp) calls serveJson with no settings-PIN check, unlike the /edit endpoint which explicitly checks correctPIN, disclosing the device's general configuration (network, hardware, LED setup) to any unauthenticated client on the network."

      "lang": "es",
      "value": "El endpoint GET /json/cfg de WLED (registrado en wled00/wled_server.cpp) llama a serveJson() sin una verificación del PIN de configuración, a diferencia del endpoint /edit que verifica explícitamente ’correctPIN’, revelando la configuración general del dispositivo (red, hardware, configuración de LED) a cualquier cliente no autenticado en la red. Por separado, el estado de desbloqueo del PIN de configuración se rastrea a través de un único booleano global ’correctPIN’ (wled00/wled.h), no por estado de sesión: una vez que cualquier cliente individual envía el PIN correcto de 4 dígitos a través de POST /json, ’correctPIN’ se vuelve verdadero para cada cliente, otorgando a todos los clientes no autenticados subsiguientes acceso completo de escritura a la configuración (actualizaciones de firmware OTA, reconfiguración de WiFi, restablecimiento de fábrica) hasta que el dispositivo se reinicie."
