Sensitive-data use via missing Shortcuts consent checks

Published Jun 10, 2024 · Updated Apr 2, 2026

Improper access control in Shortcuts in Apple iOS, iPadOS, and macOS allows attackers to use sensitive data without a consent prompt. Certain Shortcuts actions fail to perform the checks that should request user consent before using sensitive data; Apple has not disclosed the affected actions or check logic. Execution of a crafted shortcut and user interaction are required, and the documented consequence is limited to unprompted use of sensitive data.
