Worst Case
Sensitive data like passwords, authentication tokens, or confidential documents could be exfiltrated from the user's system through clipboard manipulation.
Likely Case
Malicious apps could harvest clipboard contents containing potentially sensitive information that users copy during normal operations.
If Mitigated
With proper app sandboxing and user awareness, the risk is limited to data users explicitly copy while using untrusted applications.
🎯 Exploit Status
Exploitation requires a malicious application to be installed and executed, plus user interaction to copy sensitive data.
