CVE-2026-68067 in Mira
Summary
by MITRE • 08/12/2026
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 access hormone record information and account settings.

This vulnerability represents a critical authentication flaw in the mira cloud api login endpoint that fundamentally undermines the security of user accounts and sensitive health data. The issue stems from improper validation of password inputs where the system accepts any format-valid string without proper authentication checks, effectively allowing attackers to bypass legitimate password requirements through a simple email-based account lookup mechanism. This type of vulnerability aligns with CWE-287 which addresses improper authentication issues and represents a severe deviation from secure authentication practices that should require valid credentials before granting access tokens.
The technical implementation flaw occurs at the api endpoint level where the system performs an email address lookup without validating the corresponding password field, creating a path for unauthorized account access. When an attacker submits a valid email address to the login endpoint, the system returns an active session token regardless of the password value provided, essentially treating any string as a valid password. This behavior constitutes a classic authentication bypass vulnerability that violates fundamental security principles and creates immediate risk for all accounts associated with the affected service.
The operational impact of this vulnerability is substantial as it enables attackers to gain unauthorized access to sensitive personal health information including hormone records and account settings. This represents a direct violation of user privacy and could lead to identity theft, account takeover, and potential misuse of medical data. The vulnerability affects the confidentiality and integrity of the system as attackers can not only access but potentially modify account configurations and health information. From an attacker perspective this creates a low-effort high-impact attack vector that requires minimal technical skill to exploit while providing maximum access to sensitive user data.
From a security framework perspective, this vulnerability directly relates to ATT&CK technique T1078 which covers legitimate credentials usage and represents a failure in the authentication process that should have prevented unauthorized access. The flaw also demonstrates poor input validation practices and inadequate session management controls that should be implemented according to industry standards such as those outlined in NIST SP 800-63B for authentication assurance levels. Organizations should implement proper password validation mechanisms, enforce secure session handling, and ensure that all authentication attempts require valid credential verification before issuing access tokens.
Mitigation strategies should include immediate implementation of proper password validation logic at the login endpoint, ensuring that session tokens are only issued after successful password verification. The system should be redesigned to require valid credentials for all authentication attempts while implementing rate limiting and monitoring for suspicious login patterns. Additional controls should include account lockout mechanisms after failed attempts, multi-factor authentication implementation, and regular security testing to identify similar vulnerabilities in the authentication flow. Security teams should also implement comprehensive logging of authentication events to detect and respond to unauthorized access attempts effectively while ensuring compliance with relevant data protection regulations such as HIPAA or GDPR requirements for handling sensitive health information.
