summary 
ESP-IDF web_server basic auth bypass using empty or incomplete Authorization header
On the ESP-IDF platform, ESPHome's [`web_server` authentication](https://esphome.io/components/web_server.html#configuration-variables) check can pass incorrectly when the client-supplied base64-encoded `Authorization` value is empty or is a substring of the correct value (e.g., correct username with partial password). This allows access to `web_server` functionality (including OTA, if enabled) without knowing any information about the correct username or password.

summary 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`.
