Protection disablement via unchecked broadcast intent
Published Sep 9, 2026 · Updated Sep 10, 2026
Improper intent verification in Samsung Cloud Assistant before 9.0.5 allows local users to disable enhanced data protection settings. An application broadcast receiver accepts an untrusted intent without enforcing the access-control check required before changing the setting. A malicious application running locally can therefore turn off the protection without privileges or user interaction, reducing the availability of that security control.
