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 vulnerability in Apple Shortcuts on iOS, iPadOS, and macOS allows shortcuts to access sensitive data (contacts, photos, location, etc.) without prompting the user for authorization, enabling potential unauthorized access to private information through certain shortcut actions.

MitigationApply the appropriate OS update: iOS 16.7.8 or 17.5+, iPadOS 16.7.8 or 17.5+, macOS Ventura 13.6.7+, or macOS Sonoma 14.5+ to resolve the missing authorization check in Shortcuts.

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 iOS version on iPhone
    Go to Settings > General > About > Version and note the build number
    Affected if Version is less than 16.7.8, or between 17.0 and 17.4.x (inclusive)
  2. Check iPadOS version on iPad
    Go to Settings > General > About > Version and note the build number
    Affected if Version is less than 16.7.8, or between 17.0 and 17.4.x (inclusive)
  3. Check macOS version on Mac
    Go to System Settings > About (or System Preferences > About on older macOS) and note the version
    Affected if Version is less than 13.6.7, or between 14.0 and 14.4.x (inclusive)
  4. Confirm Shortcuts usage
    Check if the Shortcuts app is installed and has been used to run shortcuts that access sensitive data (contacts, photos, location, etc.)
    Affected if Shortcuts are used to access sensitive device data on a vulnerable OS version

The device is affected if it runs iOS/iPadOS 17.0-17.4.x or below 16.7.8, or macOS 14.0-14.4.x or below 13.6.7, and the Shortcuts app is used to access contacts, photos, location or other sensitive data without user prompts.

Interim mitigation

Apply the appropriate OS update: iOS 16.7.8 or 17.5+, iPadOS 16.7.8 or 17.5+, macOS Ventura 13.6.7+, or macOS Sonoma 14.5+ to resolve the missing authorization check in Shortcuts.

Recommended fix High confidence

iOS 16.7.8 / iOS 17.5 / iPadOS 16.7.8 / iPadOS 17.5 / macOS Ventura 13.6.7 / macOS Sonoma 14.5 (depending on current version)

  1. Identify the current operating system version on the device (iOS, iPadOS, or macOS)
  2. For iOS/iPadOS 16.x users: Update to iOS 16.7.8 / iPadOS 16.7.8
  3. For iOS/iPadOS 17.x users: Update to iOS 17.5 / iPadOS 17.5
  4. For macOS Ventura (13.x) users: Update to macOS 13.6.7
  5. For macOS Sonoma (14.x) users: Update to macOS 14.5
  6. To update: Go to Settings > General > Software Update on iOS/iPadOS, or System Settings > Software Update on macOS
Caveat Standard iOS/macOS update considerations: back up device before updating, some legacy apps may not be compatible with newer OS versions
