⚠️ Risk & Real-World Impact
Worst Case
Arbitrary code execution in the context of the current user, leading to complete system compromise, data theft, or ransomware deployment.
Likely Case
Information disclosure from process memory, potentially exposing sensitive data like credentials, session tokens, or other application data.
If Mitigated
Limited information disclosure with no code execution due to ASLR/DEP protections, minimal impact on system integrity.
🎯 Exploit Status
Requires user interaction (opening malicious file). Information disclosure alone may require additional vulnerabilities for code execution.
