CVE-2021-46841Network attack vector

Activity tracking via unencrypted network transmission

Published Feb 27, 2023 · Updated Mar 11, 2025

Information disclosure in Apple Music for Android before 3.5.0 allows man-in-the-middle attackers to track a user's activity. The app sends activity information over unencrypted HTTP rather than HTTPS, allowing an on-path observer to monitor those transmissions. Exploitation requires a privileged network position, and the documented consequence is tracking user activity rather than changing data or interrupting playback.
