This vulnerability involves third-party shortcuts leveraging a legacy Automator action to send events to other applications without explicit user consent, potentially allowing unauthorized interactions between apps. Apple fixed the issue by implementing an additional user consent prompt to prevent such unauthorized event sending. The fix is included in macOS Monterey 12.7.4, Ventura 13.6.5, and Sonoma 14.4. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and low impact on confidentiality and integrity, with no impact on availability.

An attacker could craft or distribute third-party shortcuts that send events to other applications without the user’s permission, potentially leading to unauthorized actions or data access within those apps. The impact is limited to confidentiality and integrity with low severity and requires user interaction. There are no reports of active exploitation in the wild.

Apple has released official patches that address this vulnerability by adding an additional prompt for user consent. Users and administrators should update affected macOS systems to Monterey 12.7.4, Ventura 13.6.5, Sonoma 14.4, or later versions to ensure the vulnerability is remediated. No further mitigation steps are required beyond applying these official updates.
