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
This issue was addressed through improved state management. This issue is fixed in macOS Sequoia 15, macOS Sonoma 14.7, macOS Ventura 13.7. Visiting a malicious website may lead to user interface spoofing.

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 state management vulnerability in macOS WebKit allows malicious websites to spoof user interface elements. The vulnerability is triggered when a user visits a crafted website, potentially tricking them into believing they're interacting with legitimate UI components.

MitigationUpdate macOS to version 15 (Sequoia), 14.7 (Sonoma), or 13.7 (Ventura) or later to receive the state management fix. Avoid visiting untrusted websites until the update is applied.

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 installed macOS version
    Open Terminal and run: sw_vers -productVersion
    Affected if The version displayed is below 13.7, or between 14.0 and 14.6 (inclusive)
  2. Confirm macOS release name
    Run: sw_vers -productVersionExtra to see if it shows Ventura, Sonoma, or Sequoia, or check System Settings > About
    Affected if Running Ventura versions before 13.7, or Sonoma versions before 14.7, or any version below 13.7 regardless of name
  3. Identify WebKit-based browsers in use
    Check for Safari, or any third-party browsers that use WebKit (common on macOS). Look in /Applications folder or run: defaults read /Applications/Safari.app/Contents/Info CFBundleIdentifier
    Affected if WebKit-based browsers are installed and used, combined with a vulnerable macOS version from steps 1-2
  4. Verify Safari WebKit engine
    Open Safari, go to Safari > Settings > Advanced, enable Show Develop menu, then Develop > WebKit Version in menu bar
    Affected if The WebKit version cannot be separately checked on macOS - the vulnerability is tied to macOS version, not separate WebKit version

If macOS version is 13.7 or higher, 14.7 or higher, or 15 (Sequoia) or higher, the environment is NOT affected; any version below 13.7 or between 14.0 and 14.6 IS affected when using WebKit-based browsers.

Upgrade available Upgrade to 13.7 / 14.7 or later
Fixed in 13.714.7
Interim mitigation

Update macOS to version 15 (Sequoia), 14.7 (Sonoma), or 13.7 (Ventura) or later to receive the state management fix. Avoid visiting untrusted websites until the update is applied.

Recommended fix High confidence

macOS Ventura 13.7, macOS Sonoma 14.7, or macOS Sequoia 15

  1. Identify your current macOS version by clicking the Apple menu and selecting 'About This Mac'
  2. Back up important data before performing any system update
  3. Determine which upgrade path applies based on your current version: If running macOS Ventura (13.x), update to 13.7 or later; If running macOS Sonoma (14.0-14.6), update to 14.7 or later; If running macOS Sequoia (15.x), no action needed as it is already fixed
  4. Open System Settings > General > Software Update to check for and install the available update
  5. Restart your Mac if prompted to complete the installation
Caveat Standard macOS update considerations apply - verify application compatibility with new OS version before deploying in production environments
