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
A cross-origin issue in the IndexDB API was addressed with improved input validation. This issue is fixed in iOS 15.3 and iPadOS 15.3, watchOS 8.4, tvOS 15.3, Safari 15.3, macOS Monterey 12.2. A website may be able to track sensitive user information.

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

A cross-origin vulnerability in the IndexDB API allowed websites to improperly access IndexedDB databases from other origins due to insufficient input validation. This could enable a malicious website to track users by accessing sensitive data stored by other sites in the browser's IndexedDB storage.

MitigationApply vendor-supplied updates: upgrade to iOS 15.3+, iPadOS 15.3+, watchOS 8.4+, tvOS 15.3+, Safari 15.3+, or macOS Monterey 12.2+. For web applications, implement Content Security Policy and SameSite cookie attributes as defense-in-depth.

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. Identify the Apple browser product in use
    Determine if you are using Safari, Safari on iOS/iPadOS, or a WebKit-based browser on macOS. On iOS devices, check Settings > Safari > About. On macOS, check Safari > About Safari. On tvOS/watchOS, check the Settings app for the browser version.
    Affected if The browser is any Apple WebKit-based browser including Safari on iOS, iPadOS, macOS, tvOS, or watchOS.
  2. Check the installed Safari version on macOS
    Open Safari, click Safari in the menu bar, then select About Safari. Note the version number displayed (e.g., 15.2, 15.3, 15.4).
    Affected if The version displayed is less than 15.3 (for example, 15.0, 15.1, 15.2).
  3. Check the iOS or iPadOS version on Apple mobile devices
    Go to Settings > General > About on the device. Note the iOS/iPadOS version number. Note that Safari on iOS/iPadOS uses the same version number as the operating system.
    Affected if The iOS or iPadOS version is less than 15.3 (for example, 15.0, 15.1, 15.2).
  4. Check the watchOS or tvOS version
    On Apple Watch: Open the Settings app on the watch, go to General > About. On Apple TV: Go to Settings > General > About. Note the version number.
    Affected if The watchOS version is less than 8.4, or the tvOS version is less than 15.3.
  5. Check the macOS version if Safari is bundled
    Click the Apple menu > About This Mac. The macOS version is displayed (e.g., 12.1, 12.2, 12.3). Safari on macOS is tied to the OS version in most distribution methods.
    Affected if The macOS version is less than 12.2 (for example, 12.0, 12.1).

You are affected if you are running any Apple WebKit-based browser (Safari, mobile Safari, or Safari on tvOS/watchOS) with a version number lower than the minimum fixed versions: Safari 15.3+, iOS/iPadOS 15.3+, watchOS 8.4+, tvOS 15.3+, or macOS 12.2+.
