CVE-2025-43417
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 · uneditedA path handling issue was addressed with improved logic. This issue is fixed in macOS Sonoma 14.8.4, macOS Tahoe 26.2. 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 path handling vulnerability in macOS where improper path validation could allow a malicious application to access sensitive user data outside its intended sandbox boundaries. The vulnerability involves insufficient path sanitization logic that could be exploited to traverse directories and read protected files.

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.
-
Determine your macOS versionOpen Terminal and run: sw_vers -productVersionAffected if The version displayed is lower than 14.8.4 (for example 14.8.3, 14.8.2, 14.7.x, 14.6.x, etc.)
-
Confirm macOS name and buildRun: system_profiler SPSoftwareDataType | grep -E 'System Version|Build Version'Affected if The System Version shows a version prior to macOS Sonoma 14.8.4
-
Check if any third-party security software is presentLook in /Applications for installed security or firewall applications that might provide additional path validationAffected if No additional security software is present and the OS version is below 14.8.4 (the vulnerability exists in the OS path handling itself)
You are affected if your macOS installation is any version lower than 14.8.4, as the path validation flaw exists in the operating system itself and requires no special configuration to be exploitable.

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 · scoped14.8.4
Update to macOS Sonoma 14.8.4 or macOS Tahoe 26.2 or later to patch the vulnerability. Ensure applications are only downloaded from trusted sources.
macOS Sonoma 14.8.4 (or macOS Tahoe 26.2 for compatible hardware)
- Back up your Mac using Time Machine or another backup solution before proceeding with the update
- Open System Settings (or System Preferences on older macOS versions)
- Navigate to General > Software Update
- Wait for macOS to check for available updates
- If macOS Sonoma 14.8.4 or later appears, click Update Now to download and install the security update
- Alternatively, download the macOS update installer from the Mac App Store or Apple website and run the installation manually
- Restart your Mac when prompted to complete the installation
- After restarting, verify the update was successful by checking System Settings > General > About to confirm the macOS version
