ESPHome versions 2025.9.0 through 2025.12.6 are vulnerable to a denial-of-service attack via integer overflow in the API protobuf decoder, affecting all supported microcontroller platforms (ESP32, ESP8266, RP2040, LibreTiny). Unauthenticated attackers can crash ESPHome devices by sending specially crafted packets with large field length values to bypass bounds checking when API encryption is disabled. Upgrade to version 2025.12.7 or later to remediate.
ESPHome is a system to control your ESP8266/ESP32 for Home Automation systems. Rated high severity (CVSS 8.7), this vulnerability is remotely exploitable, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
ESPHome is a system to control your ESP8266/ESP32. Rated high severity (CVSS 8.8), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.
