Local sensitive-data disclosure via authorization state mishandling

Published Mar 25, 2026 · Updated Mar 25, 2026

Authorization failure in macOS Printing before 14.8.5, 15.7.5, or 26.4 allows local users to read sensitive user data. The Printing component applies authorization decisions using incorrect state, allowing an app to access data that should be denied. Exploitation requires local code execution with low user privileges; Apple has not disclosed the affected printing operation or the specific data exposed.
