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 or iOS
    On macOS, open Safari and select Safari > About Safari. On iOS/iPadOS, go to Settings > Safari > About. Note the version number displayed.
    Affected if The version is earlier than 18.2 (e.g., 18.1.x, 18.0.x, or any 17.x version)
  2. Check iOS or iPadOS version
    Go to Settings > General > About > Version on the device. Note the OS version number.
    Affected if The version is earlier than 18.2 (for example, 18.1, 17.x) - note that 17.7.6 is also patched so check if below 17.7.6 if staying on iOS 17 branch
  3. Check macOS version
    Click the Apple menu > About This Mac. Note the macOS version (such as 15.1, 15.0).
    Affected if The macOS version is 15.0 or 15.1 (versions 15.0 through 15.1.x are vulnerable, fixed in 15.2)
  4. Check tvOS version
    Open Settings > General > About > Version on the Apple TV device.
    Affected if The version is earlier than 18.2 (such as 18.1, 18.0, or earlier)
  5. Check visionOS version
    Open Settings > General > About > Version on the Apple Vision Pro device.
    Affected if The version is earlier than 2.2 (such as 2.1, 2.0, or earlier)
  6. Check watchOS version
