Worst Case
Malicious applications could access sensitive user data including passwords, personal documents, or authentication tokens stored on the system.
Likely Case
Malware or compromised legitimate applications could exfiltrate user data from the local system.
If Mitigated
With proper application sandboxing and user permission controls, impact would be limited to data accessible by already-trusted applications.
🎯 Exploit Status
Exploitation requires an attacker to get a malicious application installed and executed on the target system. No remote exploitation vector exists.
