CVE-2021-25357

Contact disclosure via implicit PendingIntent hijacking

Published Apr 9, 2021 · Updated Aug 3, 2024

PendingIntent hijacking in Create Movie on affected Samsung Mobile Devices allows unprivileged applications to read contact information. Create Movie places an implicit Intent inside a PendingIntent, allowing another installed application to intercept it instead of the intended component. Exploitation requires an unprivileged application to run locally on the device; the documented consequence is unauthorized contact access.
