CVE-2025-43279
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 privacy issue was addressed with improved private data redaction for log entries. 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 confidenceA privacy vulnerability in macOS Tahoe 26 allowed applications to access user-sensitive data through log entries that were not properly redacted. The issue involved inadequate private data redaction in system logs, potentially exposing personally identifiable information or other sensitive user data to malicious or compromised applications.

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.
-
Check installed macOS versionRun 'sw_vers -productVersion' in Terminal or check System Settings > General > AboutAffected if The version displayed is below 26.0 (for example, 25.x, 24.x, etc.)
-
Verify system update statusCheck System Settings > General > Software Update for pending security updatesAffected if A security update for macOS is available but not yet installed
-
Confirm macOS codenameRun 'sw_vers -buildVersion' and cross-reference with Apple's macOS build tables to confirm it is pre-Tahoe 26Affected if The build corresponds to a macOS version released before the Tahoe 26 update
Your environment is affected if the installed macOS version is lower than 26.0, as this indicates the inadequate log redaction vulnerability is present.
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 · scoped26.0
Update to macOS Tahoe 26 or later. Organizations should deploy the security update across all affected macOS devices to remediate the improper log redaction.
macOS Tahoe 26.0
- Back up important data using Time Machine or another backup solution
- Verify your Mac model is supported by macOS Tahoe 26.0 (check Apple's compatibility list)
- Ensure at least 20GB of free disk space is available
- Connect your Mac to power adapter
- Open System Settings > General > Software Update
- Click 'Update Now' or 'Upgrade Now' to download and install macOS Tahoe 26.0
- Restart your Mac when prompted to complete the installation
- After upgrade, verify the version by going to System Settings > General > About and confirming version 26.0 or later
