Summary
Successful exploitation of these vulnerabilities could allow an attacker to access unauthorized health profile information, make changes to health information, cause a denial-of-service condition, disclose session token information, and obtain control of user accounts.
Vulnerabilities 8
-
Critical 9.8
Mira Hormone Monitor, Mira Android App Weak Authentication
The login endpoint on the Mira cloud API accepts any format-valid string in the password field and returns a live active session token for the account matching the supplied email address. An attacker could use an email address to control cloud accounts and ac…
-
Critical 9.1
Mira Hormone Monitor, Mira Android App Use of Hard-coded Credentials
The distributed Mira Android APK v4.5.15.4 allows an attacker read/write access to reproductive health profiles from internet connected hosts, which could result in forgery, deletion, or destruction of health information.
-
High 8.8
Mira Hormone Monitor, Mira Android App Missing authentication for critical function
In the Mira hormone monitor device firmware v1.7.1.47 build 01070147, a remote unauthenticated attacker within BLE range (approximately 10–30 meters) can silently rebind the device to an attacker-controlled account, extract stored hormone measurements in clea…
-
High 7.4
Mira Hormone Monitor, Mira Android App Authentication bypass by spoofing
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…
-
Medium 6.5
Mira Hormone Monitor, Mira Android App Missing authentication for critical function
The Mira hormone monitor device firmware accepts a 0x01 write from any BLE central without authentication, causing the device to reboot into bootloader mode. An attacker could cause a denial-of-service condition or disrupt ovulation tracking and fertility mon…
-
Medium 6.5
Mira Hormone Monitor, Mira Android App Use of GET request method with sensitive query strings
When the Mira Android app opens in-app WebView content (e.g., shop redirect flows), the user's live session token is appended to the URL as a query string parameter, and a persistent user identifier is included in the WebView's User-Agent header. Both are the…
-
Medium 5.3
Mira Hormone Monitor, Mira Android App Improper restriction of excessive authentication attempts
The Mira cloud authentication endpoints do not enforce per-account rate limiting, per-IP throttling, or account lockout after repeated failed login attempts. An attacker can use brute-force methods to obtain gain access to user accounts.
-
Medium 4.3
Mira Hormone Monitor, Mira Android App Reliance on untrusted inputs in a security decision
The Mira cloud API accepts the firmware version reported by the companion app as authoritative for a given device, without independently attesting the version from the device itself. An authenticated attacker could submit arbitrary firmware version strings fo…
