CVE-2026-66098: CWE-306 in Quanovate Tech Inc. (operating as Mira / Mira Care) Mira Firmware
CVE-2026-66098 is a vulnerability in the Mira hormone monitor device firmware version 1.7.1.47. The firmware accepts a specific write command (0x01) from any Bluetooth Low Energy (BLE) central device without requiring authentication, which causes the device to reboot into bootloader mode. This behavior can be exploited to cause a denial-of-service condition, disrupting ovulation tracking and fertility monitoring workflows.
AI Analysis
Technical Summary
The Mira hormone monitor firmware version 1.7.1.47 has an authentication bypass vulnerability (CWE-306) where it accepts a 0x01 write command from any BLE central device without authentication. This command triggers the device to reboot into bootloader mode, effectively causing a denial-of-service by interrupting its normal operation. The vulnerability has a CVSS 4.0 base score of 7.1, indicating high severity. No official patch or remediation guidance is currently available from the vendor or advisory sources.
Potential Impact
An unauthenticated attacker within BLE range can send a specific command to the device causing it to reboot into bootloader mode, resulting in denial of service. This disrupts the device's ability to track ovulation and fertility, potentially impacting users relying on the device for health monitoring.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit physical and wireless access to the device to trusted BLE central devices only to reduce exposure to unauthenticated commands.
