What to do this week
Concrete actions for security leads
Key Takeaways
- Hard-coded Bluetooth credentials in the Flow Neuroscience FL-100 allow unauthorized parties to bypass safety controls.
- CISA added CVE-2026-68820 to the KEV catalog, affecting Microsoft Windows networking drivers used in many imaging systems.
- Undocumented backdoors in Pulsetto Vagus Nerve Stimulators create risks of physical harm via over-stimulation.
- The Mira Hormone Monitor and its Android app suffer from session management flaws that allow remote account takeover.
- The FDA expects active monitoring of legacy hardware and prioritization of patches for privilege escalation vulnerabilities.
The discovery of hard-coded credentials and undocumented backdoors in wearable neurostimulation devices highlights a critical failure in securing local wireless protocols. Additionally, the inclusion of a Windows networking driver vulnerability in the CISA KEV catalog requires immediate patching for manufacturers using legacy Windows environments.
This week focuses on the intersection of legacy hardware vulnerabilities and active exploitation of core operating system drivers. Security leads must address authentication gaps in wearable devices that could lead to unauthorized dosage changes or physical harm through over-stimulation.
At the same time, the regulatory landscape remains focused on how manufacturers manage the communication bridge between home-use hardware and mobile applications. As more devices move toward consumer-facing mobile ecosystems, session management and firmware logic auditing have become central to maintaining patient safety and data integrity.

Why This Matters
For medical device manufacturers, these updates signal that local access is no longer a secondary concern. The FDA is increasing its scrutiny of hidden debug modes and legacy wireless protocols. Failure to secure these entry points can lead to direct clinical risks, including unauthorized alterations to neural stimulation dosages or the manipulation of sensitive fertility data.
Flow Neuroscience FL-100 Bluetooth Vulnerability
The Flow Neuroscience FL-100 headset contains hard-coded Bluetooth credentials that allow unauthorized local parties to bypass safety controls.
CISA KEV Alert for Microsoft Windows Ancillary Function Driver
CISA has added CVE-2026-68820 to its Known Exploited Vulnerabilities (KEV) catalog.
Pulsetto Vagus Nerve Stimulator Backdoor Risks
A critical failure in firmware logic has been identified in the Pulsetto Vagus Nerve Stimulator.
Mira Hormone Monitor Mobile Communication Gaps
The Mira Hormone Monitor and its associated Android app demonstrate a failure to secure the communication bridge between home-use hardware and mobile platforms.
