CVE-2025-36743

Physical command execution via unauthenticated debug interface

Published Dec 12, 2025 · Updated Dec 12, 2025

Improper access control in the debug interface of SolarEdge SE3680H allows physically proximate attackers to execute debug commands. The exposed on-chip test interface accepts commands without authentication and discloses internal system data through diagnostic access. Physical access to inverter hardware is required; the public disclosure does not identify the interface protocol, available commands, or persistence effects.
