      "value": "ESPHome is a system to control microcontrollers remotely through Home Automation systems. In version 2025.8.0 in the ESP-IDF platform, ESPHome's web_server authentication check can pass incorrectly when the client-supplied base64-encoded Authorization value is empty or is a substring of the correct value. This allows access to web_server functionality (including OTA, if enabled) without knowing any information about the correct username or password. This issue has been patched in version 2025.8.1."

      "value": "ESPHome es un sistema para controlar microcontroladores remotamente a través de sistemas de automatización del hogar. En la versión 2025.8.0 en la plataforma ESP-IDF, la comprobación de autenticación del web_server de ESPHome puede ser superada incorrectamente cuando el valor de autorización codificado en base64 proporcionado por el cliente está vacío o es una subcadena del valor correcto. Esto permite el acceso a la funcionalidad del web_server (incluyendo OTA, si está habilitado) sin conocer ninguna información sobre el nombre de usuario o la contraseña correctos. Este problema ha sido parcheado en la versión 2025.8.1."
