Worst Case
Malicious applications could access sensitive user data including personal files, credentials, or other protected information stored on the system.
Likely Case
Legitimate applications with excessive permissions could inadvertently access protected data, potentially exposing user privacy information.
If Mitigated
With proper application sandboxing and permission controls, the impact would be limited to applications already granted extensive system access.
🎯 Exploit Status
Exploitation requires a malicious or compromised application to be installed and running on the target system. No public exploit code has been identified.
