CVE-2026-76640— Unitree G1 EDU 1.5.2 BLE GATT RCE via WiFi Provisioning Stack

Quick assessment

Affected
Unitree Robotics G1 EDU
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Unitree G1 EDU是中国Unitree公司的一款智能机器人。 Unitree G1 EDU 1.5.2及之前版本存在安全漏洞，该漏洞源于BLE GATT服务器和WiFi provisioning栈中存在多个链式漏洞，包括WiFi provisioning脚本中未加引号的heredoc变量和SSID块累加器中的缓冲区溢出，攻击者可发送特制BLE写入以溢出固定BSS缓冲区，破坏相邻的mainloop函数指针分发条目，导致未经身份验证的邻近攻击者无需配对或凭据即可实现以root权限执行代码。

Vulnerability Title
Unitree G1 EDU 1.5.2 BLE GATT RCE via WiFi Provisioning Stack
Source: CVE Program / CVE List V5
Vulnerability Description
Unitree G1 EDU firmware through 1.5.2 contains multiple chained vulnerabilities in the BLE GATT server and WiFi provisioning stack that allow unauthenticated proximate attackers to achieve root code execution without pairing or credentials by exploiting an unquoted heredoc variable in the WiFi provisioning script and a buffer overflow in the SSID chunk accumulator. Attackers can send crafted BLE writes to overflow a fixed BSS buffer across BLE connections, corrupting an adjacent mainloop function pointer dispatch entry that is subsequently invoked by the cleanup path passing attacker-controlled data to system() as uid 0.
