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 configuration issue was addressed with additional restrictions. This issue is fixed in macOS Sequoia 15.6, macOS Sonoma 14.7.7. Account-driven User Enrollment may still be possible with Lockdown Mode turned on.

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 configuration issue in macOS allowed Account-driven User Enrollment (an MDM feature) to function even when Lockdown Mode was enabled, effectively bypassing the intended security restriction. This was fixed in macOS Sequoia 15.6 and macOS Sonoma 14.7.7 with additional restrictions.

MitigationApply the appropriate macOS security update (15.6 for Sequoia, 14.7.7 for Sonoma) and verify that Lockdown Mode now properly restricts Account-driven User Enrollment in MDM configurations.

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 installed macOS version
    Run 'sw_vers -productVersion' in Terminal or open System Settings > General > About to view the version number
    Affected if Version is less than 14.7.7 OR between 15.0 and 15.5 (inclusive)
  2. Verify MDM Account-driven User Enrollment is configured
    Check System Settings > General > About > Device Management, or run 'profiles status' in Terminal to see if an MDM profile with user enrollment is installed
    Affected if An MDM profile with Account-driven User Enrollment is present on the system
  3. Check if Lockdown Mode is enabled
    Open System Settings > Privacy & Security and look for the Lockdown Mode toggle, or use 'nvram -p' to check boot-args for 'lockdown-mode' setting
    Affected if Lockdown Mode is currently turned ON
  4. Confirm enrollment still works with Lockdown Mode
    With Lockdown Mode enabled, attempt to access MDM-enrolled services or check if user authentication to the MDM identity still succeeds (such as logging in with the enrolled managed Apple ID)
    Affected if User can successfully authenticate to MDM services despite Lockdown Mode being enabled - this indicates the bypass is present

You are affected if your macOS version is below 14.7.7 or between 15.0-15.5, you have MDM Account-driven User Enrollment configured, and user authentication to MDM succeeds even when Lockdown Mode is enabled.

Interim mitigation

Apply the appropriate macOS security update (15.6 for Sequoia, 14.7.7 for Sonoma) and verify that Lockdown Mode now properly restricts Account-driven User Enrollment in MDM configurations.

Recommended fix High confidence

macOS Sonoma 14.7.7 or macOS Sequoia 15.6

  1. Check current macOS version by clicking the Apple menu > About This Mac
  2. Back up critical data using Time Machine or another backup solution before proceeding with the OS upgrade
  3. Upgrade to macOS Sonoma 14.7.7 if running a version earlier than 14.7.7
  4. Upgrade to macOS Sequoia 15.6 if running macOS 15.0 through 15.5
  5. To perform the upgrade, go to System Settings > General > Software Update and install the available update
  6. Restart the device when prompted to complete the installation
  7. Verify the upgrade was successful by checking About This Mac shows the correct version number
Caveat Standard macOS upgrade risks apply - review app compatibility and ensure backups are current before upgrading
