CVE-2023-29857Public exploitNetwork attack vector

Vehicle-data disclosure via unauthenticated web interface

Published May 18, 2023 · Updated Jan 22, 2025

Information exposure in TeslaMate 1.27.1 allows remote attackers to read vehicle data by directly opening the web interface. The published demonstration locates the flaw in the web interface, which returns vehicle information without requiring credentials, but identifies no route or handler. The service must be network-reachable, and the documented consequence is read-only exposure of vehicle information rather than token access or vehicle control.
