CVE-2025-43477
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 Sequoia 15.7.2, macOS Sonoma 14.8.2, macOS Tahoe 26.1. An app may be able to access sensitive user 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 · high confidenceThis is a privacy vulnerability in macOS where log entries were not properly redacting sensitive user data before being written. An application could potentially access this unredacted sensitive information through system logs.

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 to get the exact version number (e.g., 14.7.1, 15.6.3)Affected if Version is 14.0 to 14.8.1 inclusive, or 15.0 to 15.7.1 inclusive (macOS Sonoma or Sequoia within the affected range)
-
Identify macOS build variantRun 'uname -r' to confirm the Darwin kernel version; Sonoma shows as 23.x, Sequoia shows as 24.xAffected if The Darwin version corresponds to an affected macOS release
-
Review system log configurationCheck /etc/asl/ or /var/log/ directories and run 'log show --system --last 1h | head -50' to inspect recent system logsAffected if Logs contain entries that may include unreduced sensitive user data such as credentials, tokens, or personal information
-
Check for third-party log accessRun 'ls -la /var/log/system.log' (or log stream via 'log stream') and verify which processes have read access to system logsAffected if Applications have access to system logs that may contain unredacted sensitive information
A system is affected if it runs macOS Sonoma 14.0-14.8.1 or macOS Sequoia 15.0-15.7.1, as these versions may write sensitive user data to system logs without proper redaction.

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 · scoped14.8.215.7.2
Update affected macOS systems to the patched versions: macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, or macOS Tahoe 26.1, or later.
macOS Sonoma 14.8.2 or macOS Sequoia 15.7.2 (depending on current major version)
- Back up critical data before initiating the system update
- Open System Settings > General > Software Update on the affected Mac
- Ensure the Mac is connected to power during the update process
- Install macOS Sonoma 14.8.2 if running macOS 14.x, or macOS Sequoia 15.7.2 if running macOS 15.x
- Restart the system when prompted to complete the installation
- Verify the update was successful by checking System Settings > General > About > macOS Version
