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 Safari version on macOS
    Open Safari, click Safari menu > About Safari, or run 'defaults read /Applications/Safari.app/Contents/Info.plist CFBundleShortVersionString' in Terminal
    Affected if Version is below 15.3 and macOS version is 12.0.0 or higher but below 12.2
  2. Check macOS Monterey version
    Click Apple menu > About This Mac, or run 'sw_vers -productVersion' in Terminal
    Affected if macOS version is 12.0.0, 12.1.x, or 12.2 (not yet updated to 12.2+) and Safari is unpatched
  3. Check iOS or iPadOS version on iPhone/iPad
    Go to Settings > General > About, or connect device to computer and check in Finder/iTunes
    Affected if iOS or iPadOS version is below 15.3
  4. Check tvOS version on Apple TV
    Go to Settings > General > About > Version, or check via Finder (device management)
    Affected if tvOS version is below 8.4
  5. Check watchOS version on Apple Watch
    Open Watch app on iPhone > My Watch > General > About, or check on Apple Watch in Settings > General > About
    Affected if watchOS version is below 8.4
  6. Check WebKitGTK version on Linux systems
    Run 'webkit2gtk-4.0-version' or check package manager: 'dpkg -l libwebkit2gtk-4.0-37' or 'rpm -q webkit2gtk4.0-libs'
    Affected if WebKitGTK version is below 2.36.7

You are affected if your Safari is below 15.3 on macOS 12.0-12.2, iOS/iPadOS below 15.3, tvOS below 8.4, watchOS below 8.4, or WebKitGTK below 2.36.7.
