⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining complete control over the victim's machine, including file system access, network access, and ability to install persistent malware.
Likely Case
Data theft, credential harvesting, and installation of cryptocurrency miners or other unwanted software.
If Mitigated
Limited to application-specific data exposure if proper sandboxing and content security policies are implemented.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious content) but the technical barrier is low given public PoC availability.
