Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
There is a possible information disclosure due to a missing permission check. This could lead to local information disclosure of health data with no additional execution privileges needed.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is an access control vulnerability where a missing permission check allows unauthorized local access to sensitive health data. An attacker with local access can view health information without requiring elevated privileges or authentication.

MitigationImplement proper permission and authorization checks at all access points that handle health data to verify the requesting user has appropriate access rights before returning any information.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Android devices in your environment
    Inventory all mobile devices and identify which ones run Google Android OS
    Affected if Any Android device exists in the environment that stores or accesses health data
  2. Locate health-related applications
    Review installed applications on Android devices for apps that handle health information such as fitness trackers, health monitors, medical record viewers, or wellness applications
    Affected if Any health-related application is installed on the Android device
  3. Verify health data storage
    Check if the Android device or any installed health application stores sensitive health information locally including fitness metrics, medical records, biometric data, or wellness data
    Affected if Health data is stored on or accessible through the Android device
  4. Test local access to health data
    Attempt to access health data through the application or system interfaces without providing any authentication credentials or elevated permissions
    Affected if Health data can be viewed without requiring authentication or elevated privileges
  5. Review permission configuration
    Examine the Android application permissions and system access controls for health data handling components to identify if permission checks are enforced before data is returned
    Affected if Health data is returned without verifying the requesting user has appropriate access rights

If you have Android devices with health data that can be accessed locally without authentication or permission verification, your environment is affected by this vulnerability.
