## What is CVE-2026-1354?

CVE-2026-1354 is a medium-severity authentication bypass vulnerability in Zero Motorcycles firmware, published on 21 Apr 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

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.

Weakness: CWE-322 (Key Exchange without Entity Authentication)

Check this codebase for CVE-2026-1354 and fix it if it is affected.

What it is: CVE-2026-1354 is a medium-severity authentication bypass vulnerability in Zero Motorcycles firmware, published on 21 Apr 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-1354 in the wild and no public exploit code.

Affected product: Zero Motorcycles firmware. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
