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 CFBundleShortVersionString' in Terminal
    Affected if Version is lower than 18.2
  2. Check iOS or iPadOS version
    Go to Settings > General > About on iPhone or iPad; the version number is shown next to 'Software Version'
    Affected if Version is lower than 18.2 (or not 17.7.6)
  3. Check macOS version
    Click Apple menu > About This Mac; the macOS version is shown below the operating system name
    Affected if Version is lower than 15.2 (Sequoia)
  4. Check tvOS, visionOS, or watchOS version
    On the device, go to Settings > General > About to view the tvOS, visionOS, or watchOS version
    Affected if tvOS is lower than 18.2, visionOS is lower than 2.2, or watchOS is lower than 11.2
  5. Confirm web content exposure
    Verify that Safari or any webkit-based browser is used to access the internet
    Affected if Web browsing is enabled and any of the above version conditions are true

You are affected if you run any Safari version below 18.2 or any affected Apple OS version below the patched release (macOS 15.2, iOS/iPadOS 18.2 or 17.7.6, tvOS 18.2, visionOS 2.2, watchOS 11.2) and use web browsing functionality.
