Local privilege escalation via unvalidated projection request
Published Sep 4, 2025 · Updated Sep 4, 2025
Improper input validation in Wear OS based on Android 13 and 14 allows local users to obtain a token for unauthorized screen recording. MediaProjectionPermissionActivity.onCreate accepts a malicious application's crafted input and grants a MediaProjection token without adequately validating the request. A locally installed malicious app can exploit the flaw without user interaction or additional execution privileges, allowing it to capture screen content under the token's authority.
