CVE-2026-21032

Local script execution via exported receiver

Published Jun 5, 2026 · Updated Jun 5, 2026

Improper component export in Samsung Assistant before 9.3.14 allows local users to execute arbitrary scripts through SmartHomeWidgetReceiver. SmartHomeWidgetReceiver is exported without proper access control, so untrusted Android applications can invoke its script-handling behavior. Another local Android application can reach the receiver without privileges or user interaction; the execution context and accessible data remain undisclosed.
