Shared-note disclosure via implicit intent
Published Oct 10, 2025 · Updated Oct 10, 2025
Implicit-intent exposure in Samsung Notes before 4.4.30.63 allows local attackers to access shared notes through Android IPC. The app sends sensitive note-sharing communication with an implicit intent, allowing another local app to receive data not explicitly addressed to it. No user interaction or prior privilege is required, and the reported consequence is limited to disclosure of shared-note content.
