Android Framework Tapjacking Vulnerability Leading to Unauthorized Permission Granting

A tapjacking vulnerability has been identified in the Android Framework's DefaultTransitionHandler component. This issue allows an app to unintentionally receive permissions through an overlay attack, potentially leading to unauthorized privilege escalation. The vulnerability affects several Android versions and requires user interaction for exploitation.

Impact

Exploitation of this vulnerability could result in unauthorized permission grants to an application, allowing it to escalate privileges without additional execution rights.

Reproduction

The vulnerability can be reproduced by creating an overlay that obscures a user interface element. When the user interacts with the overlaid element, the underlying app can receive permissions without the user's knowledge. This requires careful timing and placement of the overlay to intercept the user's input.

Remediation

Users can update their devices to the December 2025 security patch level to address this vulnerability.
