CVE-2025-57808
CVE-2025-57808 · ESP-IDF web_server basic auth bypass using empty or incomplete Authorization header
This page contains facts from public vulnerability sources. Check the original advisory before updating.
This page shows selected source facts. See the linked advisories for the complete description and affected versions.
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.
