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

This vulnerability in Apple's ecosystem allowed a malicious or compromised application to access sensitive user data through improper environment sanitization. The issue likely involved environment variables or environment configuration not being properly cleaned or isolated, potentially exposing sensitive information to unauthorized app access.

MitigationUpdate affected devices to the fixed versions: iOS 16.7.8/17.5+, iPadOS 16.7.8/17.5+, macOS Monterey 12.7.5/Ventura 13.6.7/Sonoma 14.5+, tvOS 17.5+, or watchOS 10.5+ as appropriate.

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 your Apple device type
    Determine whether the device is an iPhone, iPad, Mac, Apple TV, or Apple Watch. This matters because version ranges differ by platform.
    Affected if Device is any Apple product listed in the affected versions (iPhone, iPad, Mac, Apple TV, or Apple Watch)
  2. Check iOS or iPadOS version
    On iPhone or iPad, go to Settings > General > About > Version to view the installed OS version.
    Affected if Version is less than 16.7.8, OR is 17.0 through 17.4 (any version >= 17.0 and < 17.5)
  3. Check macOS version
    On Mac, click the Apple menu > About This Mac to view the installed macOS version and name (Monterey, Ventura, or Sonoma).
    Affected if Version is less than 12.7.5 (Monterey), OR 13.0 through 13.6.6 (Ventura), OR 14.0 through 14.4 (Sonoma)
  4. Check tvOS version
    On Apple TV, go to Settings > General > About > Version to view the installed tvOS version.
    Affected if Version is less than 17.5
  5. Check watchOS version
    On paired iPhone, open the Watch app > My Watch > General > About to view the watchOS version, or check directly on Apple Watch via Settings > General > About.
    Affected if Version is less than 10.5

You are affected if your device OS version falls within any of the vulnerable ranges: iOS/iPadOS < 16.7.8 or 17.0-17.4, macOS < 12.7.5 or 13.0-13.6.6 or 14.0-14.4, tvOS < 17.5, or watchOS < 10.5.
