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 versionRun 'sw_vers -productVersion' in Terminal or go to Apple menu > About This MacAffected if The version is below 14.8.3, or is 15.0 through 15.7.2 (not including 15.7.3)
-
Confirm macOS nameRun 'sw_vers -productVersionExtra' or check About This Mac to determine if the system is macOS Sonoma (14.x) or macOS Sequoia (15.x)Affected if Running macOS Sonoma below 14.8.3 or macOS Sequoia between 15.0 and 15.7.2 inclusive
-
Check if application execution restrictions are disabledGo to System Settings > Privacy & Security and verify the security setting under 'Allow applications downloaded from' - if set to 'Allow Anywhere', the system has reduced protectionsAffected if Application execution restrictions are set to 'Allow Anywhere' or similar reduced setting on an affected macOS version
You are affected if your macOS version is 14.8.3 or higher for Sonoma, or 15.7.3 or higher for Sequoia; versions below these thresholds in the affected ranges are vulnerable.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped14.8.315.7.3
Apply vendor patches by updating all affected devices to iOS 18.7.3, iPadOS 18.7.3, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3, or macOS Tahoe 26.2.
macOS Sonoma 14.8.3 or macOS Sequoia 15.7.3 (depending on currently installed major version)
- Open System Settings (or System Preferences on older macOS versions)
- Navigate to General > Software Update
- Allow the system to check for available updates
- If macOS Sonoma (14.x) is installed, look for and install the update to version 14.8.3 or later
- If macOS Sequoia (15.x) is installed, look for and install the update to version 15.7.3 or later
- Restart the Mac if prompted to complete the installation
