Blue Goat analysis
Scored with Blue Goat's medical device cybersecurity risk methodology: STRIDE classification and CVSS v4.0 exploitability, with a severity-of-harm readout for your own ISO 14971 hazard analysis.
The APG-01 BT is a Bluetooth-connected blood glucose meter. CISA's advisory covers two vulnerabilities in firmware 0x0110_v1.1.0. CISA reports the vendor did not respond to its requests to coordinate, so no fix has been published.
| CVE | What an attacker can do | STRIDE | CVSS v4.0 Exploitability | Security impact |
|---|---|---|---|---|
| CVE-2026-50034 | An attacker within BLE range can passively intercept wireless traffic and obtain health-related information (CWE-319) | Information disclosure | Medium | High |
| CVE-2026-52866 | An attacker within BLE range can occupy the device's only BLE connection slot, so legitimate users can't connect (CWE-862) | Denial of service | Medium | High |
Both published vectors need no privileges and no user action, but require Bluetooth range. That's why Exploitability reads Medium. Each has one High impact. On Blue Goat's security matrix, both are High as published.
The published vectors describe the product as CISA scored it, not your device. If you build on this product or a similar component, score your own deployment with the CVSS v4.0 environmental metrics before you rate your risk.
| Severity from your hazard analysis | Safety risk at Medium exploitability |
|---|---|
| Negligible | Low |
| Minor or Serious | Medium |
| Critical or Catastrophic | High |
Glucose readings drive insulin dosing decisions. Readings that can be intercepted, or a meter that can't sync, affects how a patient manages their diabetes.
What to check now
- Encrypt every BLE characteristic that carries health data. Cleartext BLE can be captured passively, without the device ever knowing.
- Check how your device behaves when its connection slots are occupied, and whether a legitimate user can recover.
- For APG-01 BT users, there's no vendor fix. CISA recommends following its guidance on Bluetooth technology.
- If you're not affected, record that in a VEX statement with the justification.
- Re-score each affected threat in your cybersecurity risk assessment, and carry any patient-harm result into your ISO 14971 file.
