⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise including theft of sensitive files, credential harvesting, ransomware deployment, and persistent backdoor installation.
Likely Case
Theft of project files, configuration data, and local credentials leading to lateral movement or data exfiltration.
If Mitigated
Limited file access restricted by user permissions and security controls, potentially only affecting non-sensitive project files.
🎯 Exploit Status
Exploitation requires user interaction but can be triggered through indirect prompt injection. The vulnerability is directly reachable and well-documented.
