CVE-2024-40836Network attack vector

Sensitive data access via insufficient Shortcut checks

Published Jul 29, 2024 · Updated Apr 2, 2026

Authorization bypass in Shortcuts on affected iOS, iPadOS, macOS, and watchOS releases allows attackers to access sensitive data without a prompt. The Shortcuts action-validation logic performs insufficient checks before allowing certain actions to consume sensitive data without displaying the required consent prompt. Apple has not identified the affected actions, data classes, shortcut-delivery conditions, or whether interaction is required, so exposure cannot be narrowed beyond execution of an affected shortcut.
