## Description

ESPHome is a system to control your ESP8266/ESP32. A security misconfiguration in the edit configuration file API in the dashboard component of ESPHome version 2023.12.9 (command line installation) allows authenticated remote attackers to read and write arbitrary files under the configuration directory rendering remote code execution possible. This vulnerability is patched in 2024.2.1.
