CVE-2023-27963Network attack vector

Sensitive-data access via missing action permission prompts

Published May 8, 2023 · Updated Jan 29, 2025

Missing authorization in Apple Shortcuts allows attackers to access sensitive data through actions that omit required user prompts. Affected actions fail to enforce an additional permission check before using sensitive data, so Shortcuts proceeds without presenting the expected consent prompt. Execution of a shortcut containing one of those actions is required; Apple has not disclosed the action set or the specific data sources exposed.
