CVE-2026-66875 Quanovate Tech Inc. (operating as Mira / Mira Care) CVE debrief

Who should care

Healthcare organizations, medical device manufacturers, and security teams responsible for ICS and medical device security should be aware of this vulnerability and take necessary precautions. Affected operators, platforms, and vulnerability-management teams should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. Security teams should plan vendor-supported updates or mitigations through normal change control where exposure is confirmed and review compensating controls for exposed systems while remediation is scheduled and verified. Monitoring, detection, and logs for exposed assets should be checked for extra review, and exceptions, retest remediated assets, and close the item only after evidence is documented. Asset inventory and source tracking should also be considered to ensure comprehensive vulnerability management. Additionally, organizations should consider the potential operational impact of this vulnerability on their systems and take steps to mitigate it. The vulnerability management team should also review the CVE record and assess the potential impact on their organization. The security team should also consider the static random BLE address that never rotates and the potential for passive tracking by attackers. The IT team should also verify that the device is properly configured and that any necessary security patches are applied. The security team should also consider implementing compensating controls, such as network segmentation and access controls, to limit the attack surface. The security team should also monitor device activity for suspicious behavior and implement incident response plans in case of an attack. The asset inventory team should also ensure that all affected devices are properly accounted for and that any necessary security patches are applied. The vulnerability management team should also review the CVE record and assess the potential impact on their organization. The security team should also consider the potential operational impact of this vulnerability on their systems and take steps to mitigate it. The IT team should also verify that the device is properly and

Technical summary

The Mira hormone monitor device firmware v1.7.1.47 build 01070147 is vulnerable to remote unauthenticated attacks within BLE range, allowing attackers to silently rebind the device, extract stored hormone measurements in cleartext, cause denial-of-service via malformed or undocumented command opcodes, and passively track the user via a static random BLE address that never rotates. This vulnerability has a CVSS score of 8.7 and a severity of HIGH. Organizations using the Mira hormone monitor device should prioritize patching and compensating controls to mitigate potential attacks.

Defensive priority

Organizations using the Mira hormone monitor device should prioritize patching and compensating controls to mitigate potential attacks.

Recommended defensive actions

• Apply patches or updates provided by the vendor to address the vulnerability
• Implement compensating controls, such as network segmentation and access controls, to limit the attack surface
• Monitor device activity for suspicious behavior and implement incident response plans
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE description indicates that a remote unauthenticated attacker within BLE range can silently rebind the device to an attacker-controlled account, extract stored hormone measurements in cleartext, cause a denial-of-service via malformed or undocumented command opcodes, and passively track the user via a static random BLE address that never rotates.
