Summary

CVE-2026-1354 is a medium-severity Key Exchange without Entity Authentication (CWE-322) vulnerability in Cisa (inferred from references). Its CVSS base score is 5.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Adversary-in-the-Middle (T1557); ranked at the 3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to IA-2 (Identification and Authentication (Organizational Users)) and IA-3 (Device Identification and Authentication) — see the control section below for these in your framework.

Vulnerability Data

Zero Motorcycles firmware versions 44 and prior enable an attacker to forcibly pair a device with the motorcycle via Bluetooth. Once paired, an attacker can utilize over-the-air firmware updating functionality to potentially upload malicious firmware to the motorcycle. The motorcycle…

must first be in Bluetooth pairing mode, and the attacker must be in proximity of the vehicle and understand the full pairing process, to be able to pair their device with the vehicle. The attacker's device must remain paired with and in proximity of the motorcycle for the entire duration of the firmware update.

Mitigating Controls (NIST 800-53 r5) AI

Requiring device identification and authentication before establishing connections prevents unauthenticated key exchanges with unknown devices.

Requiring unique identification and authentication of users before any privileged action stops key exchange from occurring with unauthenticated parties.

Requiring identification and authentication of non-organizational users blocks key exchange with unauthenticated external actors.

Requiring proper cryptographic key establishment and management directly stops unauthenticated key-exchange implementations.

Issuing or obtaining PKI certificates under an approved policy supplies the entity authentication missing from unauthenticated key exchange.

Verifying identity assertions mitigates the missing entity authentication in key exchange.

PR.DS-02 partial match

prevents

Use of cryptography mandates authenticated key-exchange mechanisms, directly addressing the lack of entity authentication.

finds

Security testing can detect missing entity authentication during key exchange.

prevents

Secure authentication directly prevents unauthenticated key exchange by requiring verified identities before keys are established.

prevents

Identity management provides the verified identities required before key exchange occurs.

mitigates

Network security policies can require authenticated channels, indirectly reducing the risk of unauthenticated key exchange.

mitigates

Security of network services includes requirements for authenticated key exchange in service protocols.
