CVE-2025-43508
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 logging issue was addressed with improved data redaction. This issue is fixed in 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 · moderate confidenceThis is a logging vulnerability in macOS where sensitive user data could be exposed through logs due to improper data redaction. An application may be able to access this sensitive user data that was being logged without proper sanitization. The fix in macOS Tahoe 26.1 implements improved data redaction in logging mechanisms.

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' in Terminal or check System Settings > General > AboutAffected if Version displayed is exactly 26.0 (macOS Tahoe 26.0)
-
Confirm macOS is not updatedCompare your version against 26.1 - if the build number is lower than the 26.1 security update, the fix is not appliedAffected if System shows version 26.0 or build number predating the 26.1 security update
-
Assess log access by applicationsCheck if any third-party or built-in applications on the system have permissions to read system logs via the log command, Console app, or log archive filesAffected if Applications with log read access exist on macOS 26.0
Environment is affected if running macOS Tahoe version 26.0 with applications that can access system logs, as the improper data redaction in that version may have exposed sensitive user data in logs.

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 · scopedApply the macOS Tahoe 26.1 security update to address the logging data redaction issue. Organizations should review application logs for potential sensitive data exposure prior to patching.
macOS Tahoe 26.1
- Upgrade macOS 26.0 to macOS Tahoe 26.1 by installing the latest system update from System Settings > General > Software Update
