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
ArcSearch for Android versions prior to 1.12.7 could display a different domain in the address bar than the content being shown, enabling address bar spoofing after user interaction via crafted web content.

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 · high confidence

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. Verify ArcSearch for Android is installed
    Check your device for the Arc Search app (Thebrowser Arc Search) in your app list or installed applications settings
    Affected if ArcSearch for Android is not installed on the device - not affected. If installed, continue to version check.
  2. Determine installed ArcSearch version
    Go to Android Settings > Apps > Arc Search > App info, or open the Play Store and search for Arc Search to view the installed version number
    Affected if Unable to determine version - assume potentially affected if app is present
  3. Compare version against affected range
    Compare your installed version number to the affected range: any version below 1.12.7 (such as 1.12.6, 1.12.5, etc.) is within the affected range
    Affected if Installed version is less than 1.12.7 (e.g., 1.12.6, 1.12.0, 1.11.0, etc.) - the device is affected by the address bar spoofing vulnerability

You are affected if ArcSearch for Android is installed and the version is below 1.12.7, as the address bar can display a different domain than the actual content being rendered.
