Secure prompt clickjacking protection bypass
Published Sep 14, 2026 · Updated Sep 14, 2026
Clickjacking protection bypass in Foundation in Apple macOS before 27 allows local users to manipulate secure prompts via a malicious app. Foundation mishandles secure-prompt state and fails to preserve clickjacking protection, although Apple has not disclosed the exact faulty state transition. A malicious app must execute locally; the documented consequence is limited to bypassing protections around secure prompts.
