Cross-user screen disclosure via flawed state management

Published Dec 11, 2024 · Updated Apr 2, 2026

State-management flaw in Apple macOS Screen Sharing Server allows remote authenticated users to view another user's screen. Apple states that improved state management fixed the issue but has not disclosed the incorrect state transition or missing validation. Screen Sharing must be enabled and access already granted; the reported consequence is viewing a different user's screen, not control or modification.
