## What is CVE-2026-78306?

CVE-2026-78306 is a high-severity authentication bypass vulnerability in DJI Air 3, published on 24 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

DJI drones expose an unauthenticated DUML command interface over Bluetooth that allows an attacker within Bluetooth range to modify Wi-Fi configuration parameters, including the SSID, PSK, MAC address, regulatory country code, and wireless channel. An attacker can overwrite the Wi-Fi PSK with a known value and connect to the drone's internal Wi-Fi network, potentially gaining access to the flight control interface and issuing flight commands. Crafted DUML commands can also disable or restart the Wi-Fi and Bluetooth interfaces, disconnect Wi-Fi clients, or reset wireless configuration, resulting in a denial-of-service condition that can disrupt the operator's wireless control, video, and telemetry connections during flight.

Affected models are DJI Neo until 01.00.0400, DJI Neo 2 until 01.00.0500, DJI Flip until 01.00.1200, DJI Air 3 until 01.00.1600, DJI Air 3S until 01.00.1400, DJI Avata 2 until 01.00.0400, DJI Avata 360 until 01.00.0300, DJI Mavic 3 until 01.00.1400, DJI Mavic 3 Classic until 01.00.0800, DJI Mavic 3 Pro until 01.01.0700, DJI Mavic 4 Pro until 01.00.0500, DJI Mini 2 until 01.07.0200, DJI Mini 3 until 01.00.0500, DJI Mini 3 Pro until 01.00.0900, DJI Mini 4 Pro until 01.00.1100, and DJI Mini 5 Pro until 01.00.0600.

Remediation requires a firmware update from the vendor.

Weakness: CWE-306 (Missing Authentication for Critical Functionality)

```text
Check this codebase for CVE-2026-78306 and fix it if it is affected.

What it is: CVE-2026-78306 is a high-severity authentication bypass vulnerability in DJI Air 3, published on 24 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-78306 in the wild and no public exploit code.

Affected product: DJI Air 3. 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.
