28 Sep 2021 — ESPHome is a system to control the ESP8266/ESP32. Anyone with web_server enabled and HTTP basic auth configured on version 2021.9.1 or older is vulnerable to an issue in which `web_server` allows over-the-air (OTA) updates without checking user defined basic auth username & password. This issue is patched in version 2021.9.2. As a workaround, one may disable or remove `web_server`.

23 Jul 2020 — An encryption-bypass issue was discovered on Espressif ESP-IDF devices through 4.2, ESP8266_NONOS_SDK devices through 3.0.3, and ESP8266_RTOS_SDK devices through 3.3. Broadcasting forged beacon frames forces a device to change its authentication mode to OPEN, effectively disabling its 802.11 encryption. Se detectó un problema de omisión de cifrado en dispositivos Espressif ESP-IDF versiones hasta 4.2, dispositivos ESP8266_NONOS_SDK versiones hasta 3.0.3 y dispositivos ESP8266_RTOS_SDK versiones hasta 3.3.
