CVE-2026-67558 PUBLISHED

Mira Hormone Monitor, Mira Android App Authentication bypass by spoofing

Assigner: icscert
Reserved: 03.08.2026 Published: 11.08.2026 Updated: 11.08.2026

The Mira Android companion app v4.5.15.4 identifies the paired Mira hormone analyzer by performing a substring match against the BLE advertisement name only, with no cryptographic peripheral authentication, MAC allowlist, or bonded-identity check. An attacker could capture live session token information and inject forged hormone measurements into the victim's cloud record and clinical trend view.
