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
Insufficient policy enforcement in Omnibox in Google Chrome on iOS prior to 83.0.4103.88 allowed a remote attacker to perform domain spoofing via a crafted URI.

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

Insufficient policy enforcement in the Omnibox (address bar) component of Google Chrome on iOS allowed a remote attacker to perform domain spoofing via a crafted URI. The vulnerability enabled the address bar to display a different domain than the one the user was actually visiting, facilitating phishing attacks.

MitigationUpdate Google Chrome on iOS to version 83.0.4103.88 or later to obtain the patched browser.

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 Chrome iOS version
    Open Chrome on iOS, tap the three dots menu, go to Settings, then scroll to the bottom to find the version number under 'Chrome'
    Affected if Version displayed is less than 83.0.4103.88
  2. Check Chromium package version on Debian 9
    Run command: dpkg -l | grep chromium or apt-cache policy chromium
    Affected if Installed chromium version is lower than the version bundled in Chrome 83.0.4103.88 for iOS (specific Debian package version numbers vary by repository)
  3. Check Chromium package version on Debian 10
    Run command: dpkg -l | grep chromium or apt-cache policy chromium
    Affected if Installed chromium version is lower than the version bundled in Chrome 83.0.4103.88 for iOS (specific Debian package version numbers vary by repository)
  4. Verify address bar behavior if version cannot be determined
    Visit a known website and observe if the address bar shows the expected domain; manually verify URL displayed matches the actual page content
    Affected if Address bar displays a different domain than the one actually being visited

User is affected if Chrome on iOS is below version 83.0.4103.88, or if the Chromium browser package on Debian 9 or 10 is at a version corresponding to the unpatched Chrome release.
