CVE-2026-56428

The SSH service on BSH ELP (Electronic Platform) modules contains a platform-specific vulnerability due to an improperly secured default configuration. An insecure, non-revocable SSH public key is included in the firmware's authorized_keys file for the root user. An attacker in possession of the corresponding private key could leverage it to bypass authentication and gain root-level access to the appliance.
