CVE-2025-43207
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 · uneditedThis issue was addressed with improved entitlements. This issue is fixed in macOS Tahoe 26. An app may be able to access user-sensitive data.
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 confidenceThis is a macOS entitlements vulnerability where an application could improperly access user-sensitive data due to insufficient permission boundaries in the operating system. The fix in macOS Tahoe 26 involved improving the entitlements model to restrict such access.

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 macOS versionRun 'sw_vers -productVersion' in Terminal or check System Settings > AboutAffected if The version is below 26.0 (e.g., 25.x, 24.x, etc.)
-
Review installed application entitlementsInspect /Applications/*.app/Contents/Entitlements/*.plist files for any apps with broad data access permissions such as com.apple.security.personal-information.addressbook, com.apple.security.personal-information.photos-library, or similar sensitive data entitlementsAffected if Applications possess entitlements granting access to user contacts, photos, calendar, or other sensitive data without documented justification
-
Verify application sandbox statusRun 'codesign -dvv /path/to/application.app 2>&1 | grep -i sandbox' to check if an app is sandboxed, or inspect the com.apple.security.app-sandbox entitlement in the app's entitlements fileAffected if Applications handling sensitive data are not sandboxed or have sandboxing disabled
-
Audit third-party applications with full disk accessCheck System Settings > Privacy & Security > Full Disk Access for any third-party applications granted access to user data directoriesAffected if Third-party applications have Full Disk Access permissions that exceed their functional requirements
-
Inspect system-wide entitlement configurationCheck /System/Library/Frameworks/*/Resources/Entitlements/*.plist for any misconfigured system framework entitlements that may allow unauthorized data accessAffected if System frameworks contain entitlements permitting broader data access than intended
A system is affected if it runs macOS versions prior to 26.0 and has applications with entitlements or permissions that could exploit insufficient permission boundaries to access user-sensitive data.

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 · scoped26.0
Update to macOS Tahoe 26 or later to receive the entitlements fix. Verify that application sandboxing and entitlement configurations are functioning as intended.
macOS Tahoe 26.0
- Back up your Mac using Time Machine or another backup method before updating
- Open System Settings (or System Preferences on older macOS versions)
- Navigate to General > Software Update
- Allow macOS to check for available updates
- If macOS Tahoe 26.0 or later is available, click 'Update Now' or 'Upgrade Now' to install the update
- Restart your Mac if prompted to complete the installation
- After updating, verify the macOS version by going to System Settings > General > About and confirm the version number is 26.0 or later
