CVE-2023-26979

Stimulation intensity manipulation via BLE message tampering

Published Aug 3, 2023 · Updated Jul 9, 2026

Man-in-the-middle exposure in Bluetens BluetensQ 4.3.15 allows physically proximate attackers to alter stimulation intensity over BLE. The BLE control channel accepts intensity-changing messages without adequately verifying message integrity, allowing intercepted traffic to be modified in transit. The attacker must be within Bluetooth range and successfully hijack the app-to-stimulator exchange; the documented consequence is unauthorized intensity adjustment rather than data disclosure or service interruption.
