Description
Since the encryption algorithm used to protect firmware updates is itself encrypted using key material available to an attacker (or anyone paying attention), the firmware updates may be altered by an unauthorized user, and then trusted by a Unitree product, such as the Unitree Go2 and other models. This issue appears to affect all of Unitree’s current offerings as of February 26, 2026, and so should be considered a vulnerability in both the firmware generation and extraction processes. At the time of this release, there is no publicly-documented mechanism to subvert the update process and insert poisoned firmware packages without the equipment owner’s knowledge.
Analysis
Unitree robotics firmware updates can be modified and executed by local attackers due to inadequate encryption of the firmware protection mechanism, allowing arbitrary code execution on affected Go1 and Go2 models. Public exploit code exists for this vulnerability, and no patch is currently available. …

Remediation
Within 24 hours: Inventory all Unitree devices in your environment and isolate them from critical networks if possible. Within 7 days: Restrict physical access to Unitree devices, disable remote firmware update capabilities if supported, and implement network segmentation to limit lateral movement if a device is compromised. …
