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 with improved redaction of sensitive information. This issue is fixed in macOS Monterey 12.7.2, macOS Ventura 13.6.3, iOS 17.2 and iPadOS 17.2, tvOS 17.2, watchOS 10.2, macOS Sonoma 14.2. An app may be able to access user-sensitive data.

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 vulnerability in multiple Apple operating systems where an application could access user-sensitive data due to insufficient redaction of sensitive information in system components. The issue was addressed by implementing improved redaction mechanisms to properly protect sensitive user data from unauthorized application access.

MitigationApply the available security updates: macOS Monterey 12.7.2+, macOS Ventura 13.6.3+, iOS/iPadOS 17.2+, tvOS 17.2+, watchOS 10.2+, or macOS Sonoma 14.2+. No configuration-based workarounds exist; OS patching is required.

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 operating system
    Determine which Apple OS is running on the device: iOS (iPhone), iPadOS (iPad), macOS, tvOS, or watchOS. On macOS, run 'sw_vers' in Terminal. On iOS/iPadOS, go to Settings > General > About. On tvOS, go to Settings > General > About. On watchOS, use the Watch app on iPhone: My Watch > General > About.
    Affected if Any Apple operating system listed in the affected products
  2. Check the installed iOS or iPadOS version
    On iPhone or iPad, go to Settings > General > About and note the version number (e.g., 17.1.1). Compare against the fixed version 17.2.
    Affected if Version is less than 17.2 (e.g., 17.1, 16.x, etc.)
  3. Check the installed macOS version
    On Mac, go to System Settings > About (or System Preferences > About on older macOS) and note the version number (e.g., 13.5). Alternatively, run 'sw_vers' in Terminal to get the exact version.
    Affected if Version is 12.0 to 12.7.1, 13.0 to 13.6.2, or 14.0 to 14.1 (all versions below the fixed releases)
  4. Check the installed tvOS version
    On Apple TV, go to Settings > General > About and note the version number. Compare against the fixed version 17.2.
    Affected if Version is less than 17.2
  5. Check the installed watchOS version
    On paired iPhone, open the Watch app, go to My Watch > General > About and note the version number. Compare against the fixed version 10.2.
    Affected if Version is less than 10.2

The device is affected if the installed Apple OS version is lower than the fixed version (iOS/iPadOS/tvOS/watchOS below 17.2/10.2, or macOS below 12.7.2/13.6.3/14.2), since the vulnerability lies in insufficient redaction of sensitive data in system components that cannot be mitigated via configuration.

Apply the available security updates: macOS Monterey 12.7.2+, macOS Ventura 13.6.3+, iOS/iPadOS 17.2+, tvOS 17.2+, watchOS 10.2+, or macOS Sonoma 14.2+. No configuration-based workarounds exist; OS patching is required.

Recommended fix High confidence

macOS Monterey 12.7.2 / macOS Ventura 13.6.3 / macOS Sonoma 14.2 / iOS 17.2 / iPadOS 17.2 / tvOS 17.2 / watchOS 10.2

  1. Check current device OS version in Settings > General > About (iOS/iPadOS) or System Preferences > About (macOS)
  2. Back up important data using iCloud Backup or Time Machine before updating
  3. For iPhone/iPad: Go to Settings > General > Software Update and install iOS 17.2/iPadOS 17.2
  4. For Mac: Open System Settings > General > Software Update and install the appropriate version (12.7.2 for Monterey, 13.6.3 for Ventura, or 14.2 for Sonoma)
  5. For Apple TV: Go to Settings > System > Software Updates and install tvOS 17.2
  6. For Apple Watch: Open the Watch app on iPhone, go to General > Software Update and install watchOS 10.2
Caveat Standard OS update; ensure compatible apps before upgrading older macOS versions
