Main Content

### Introduction
In a concerning development for smart vehicle security, Zero Motorcycles has disclosed a critical vulnerability in its firmware that exposes motorcycles to potential Bluetooth-based attacks. The flaw, tracked as CVE-2026-1354, affects firmware versions 44 and prior, allowing attackers to pair unauthorized devices and manipulate firmware updates. This vulnerability highlights the growing risks associated with connected vehicles and the importance of robust cybersecurity measures in transportation systems.


### Key Points
- Vulnerability Impact: Successful exploitation could allow attackers to pair a device via Bluetooth, gaining unauthorized access to all Bluetooth functions, including firmware updates.
- Affected Versions: Zero Motorcycles firmware versions 44 and prior.
- Attack Complexity: High—attackers must be in proximity to the motorcycle during Bluetooth pairing and firmware updates.
- Mitigation: Zero Motorcycles recommends pairing devices in secure locations and updating firmware to the latest version, scheduled for release in May 2026.
- CVSS Score: 6.4 (Medium Severity).


### Technical Details
The vulnerability stems from a Key Exchange without Entity Authentication flaw (CWE-322) in the Bluetooth pairing process of Zero Motorcycles firmware. Attackers can exploit this weakness to forcibly pair their device with a motorcycle when it is in Bluetooth pairing mode. Once paired, the attacker can leverage over-the-air (OTA) firmware update functionality to upload malicious firmware.

Conditions for Exploitation:
- The motorcycle must be in Bluetooth pairing mode.
- The attacker must be in close proximity to the vehicle.
- The attacker must understand the full pairing process.
- The attacker’s device must remain paired and in proximity during the entire firmware update process.


### Impact Assessment
#### Potential Risks
- Unauthorized Access: Attackers could gain control over Bluetooth-enabled functions, including firmware updates.
- Malicious Firmware: The ability to upload malicious firmware could lead to vehicle malfunction, data theft, or safety risks.
- Transportation Sector Threat: As part of the Transportation Systems critical infrastructure sector, this vulnerability poses broader risks to connected vehicle ecosystems.

#### Scope of Impact
- Global Deployment: Zero Motorcycles are deployed worldwide, increasing the potential attack surface.
- High Attack Complexity: While the vulnerability requires proximity and specific conditions, the consequences of exploitation are severe.


### Mitigation Steps
Zero Motorcycles has provided the following recommendations to mitigate the risk of exploitation:

1. Secure Pairing Environment:
- Pair your mobile device with the motorcycle in a safe, controlled location where unauthorized pairing attempts are unlikely.
- Complete the full pairing process and verify its success.

2. Physical Security:
- Store physical keys in a secure location.
- Avoid leaving the motorcycle unattended with the key in the "ON" position.

3. Firmware Update:
- Update to the latest firmware version as soon as it becomes available in May 2026.

4. Monitor for Suspicious Activity:
- Be vigilant for unusual Bluetooth pairing requests or unexpected firmware update prompts.


### Affected Systems
- Vendor: Zero Motorcycles
- Product: Zero Motorcycles Firmware
- Affected Versions: 44 and prior
- Product Status: Known Affected


## Conclusion
The discovery of CVE-2026-1354 underscores the critical need for robust cybersecurity measures in connected vehicles. While the vulnerability requires specific conditions for exploitation, its potential impact on vehicle safety and functionality cannot be understated. Zero Motorcycles users are strongly encouraged to follow the recommended mitigation steps and update their firmware as soon as the patch is released.

As the transportation sector continues to embrace smart technology, vulnerabilities like this serve as a reminder of the importance of proactive cybersecurity strategies and defense-in-depth approaches to safeguard critical infrastructure.
