CVE-2023-21445

Privileged file write via implicit intent

Published Feb 9, 2023 · Updated Mar 24, 2025

Improper access control in Samsung MyFiles before 12.2.09, 13.1.03.501, or 14.1.00.422 allows local users to write privileged files. An implicit intent exposes a file-writing operation without proper access control, allowing another local application to make MyFiles perform the write under its privileges. Triggering the flaw requires local execution and user interaction; the published impact is limited to unauthorized file writes, with no reported code execution or service interruption.
