**Name of the Vulnerable Software and Affected Versions** Bluetens Electrostimulation Device BluetensQ device app version 4.3.15 **Description** The issue allows attackers to perform Man-in-the-middle attacks in the BLE channel, enabling them to decrease or increase the intensity of the stimulator by hijacking the BLE communication. **Recommendations** For version 4.3.15, consider restricting access to the BLE channel to minimize the risk of exploitation until a patch is available. As a temporary workaround, avoid using the BluetensQ device app for critical stimulation tasks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
