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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed macOS versionGo to Apple menu > About This Mac, or run 'sw_vers' in TerminalAffected if The version displayed is less than 14.8.4, or is 15.0 through 15.7.3
-
Confirm full version numberRun 'system_profiler SPSoftwareDataType' in Terminal to see the exact marketing version and build numberAffected if The build number corresponds to an unpatched version (< 24G93 for 14.x, or < 24G5024a for 15.x)
-
Check for available security updatesOpen System Settings > Software Update, or run 'softwareupdate --list' in TerminalAffected if Security Update macOS <version> is available but not yet installed
You are affected if your macOS version is either below 14.8.4 (Sonoma) or between 15.0 and 15.7.4 (Sequoia), indicating the authorization state validation fix has not been applied.

dbcve · scoped14.8.415.7.4
Apply the macOS security updates (Sequoia 15.7.4, Sonoma 14.8.4, or Tahoe 26) to patch the authorization flaw and prevent unauthorized access to sensitive user data.
macOS Sonoma 14.8.4 or macOS Sequoia 15.7.4 (or later); macOS Tahoe 26 if applicable
- Open System Settings (or System Preferences on older macOS versions)
- Click on General > Software Update
- Wait for macOS to check for updates
- If updates are available, click Download and Install
- Restart your Mac when prompted to complete the installation
- After restarting, verify the update by going to System Settings > General > About and confirming the version number matches 14.8.4 (Sonoma) or 15.7.4 (Sequoia) or later
