# Apple macOS: flawed user attribute validation lets an app gain root

An authentication check in macOS did not properly validate user attributes, which Apple fixed in several macOS releases. A malicious app running on the Mac may be able to gain root privileges.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `sw_vers -productVersion` and compare against the fixed versions listed in the fix field
- Check Software Update in System Settings for pending macOS updates

## Fix

- Update macOS to `27.2` (Golden Gate), `15.8.2` (Sequoia), or `26.7.2` (Tahoe) or later

## Timeline
