Persistent website permission dialog after navigation

Published Jun 10, 2024 · Updated Apr 2, 2026

UI state flaw in Apple Safari before 17.5 allows remote attackers to leave a site's permission dialog visible after navigation. The same Safari component affects macOS Sonoma before 14.5 and visionOS before 1.2; Apple discloses only improved checks, not the faulty operation or a patch diff. A user must visit a site that presents the dialog and then navigate away; the documented impact is persistent misleading UI, with no reported data access or code execution.
