CVE-2026-18844 rates 8.1 on CVSS v3.1. The Pulsetto vagus nerve stimulator’s firmware accepts undocumented Bluetooth Low Energy commands with no authentication, letting anyone in range disable electrical safety mechanisms or change stimulation output. Every version is affected, CISA got no answer from the vendor, and no patch exists.
