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
In validationtools, there is a possible missing permission check. This could lead to local information disclosure 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

A missing permission check in the validationtools component allows local users to access sensitive information without elevated privileges. The vulnerability stems from inadequate access controls that should restrict data based on user permissions.

MitigationImplement proper permission checks in validationtools to ensure users can only access data they are authorized to view.

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. Check Android version
    Go to Settings > About Phone > Android version or run 'getprop ro.build.version.release' via ADB shell
    Affected if Version is exactly 11.0, 12.0, or 13.0
  2. Identify validationtools component
    Search for validationtools in installed packages via 'pm list packages | grep validationtools' or check /system/priv-app for validationtools.apk in ADB shell
    Affected if The validationtools component is present on the device
  3. Verify component accessibility
    Check permissions on the validationtools component using 'dumpsys package validationtools' and review the declared permissions in the manifest
    Affected if Component declares no permission requirements or allows any installed app to access it
  4. Test information disclosure
    Attempt to invoke validationtools functions via ADB or an app to see if sensitive data is returned without elevated privileges
    Affected if Sensitive data or restricted information is accessible without granting elevated permissions

A device is affected if it runs Android 11.0, 12.0, or 13.0 and has the validationtools component installed with missing or inadequate permission checks.
