⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with remote code execution, allowing attackers to install malware, exfiltrate data, or pivot to other systems.
Likely Case
Limited command execution within user context, potentially leading to data theft, privilege escalation, or lateral movement.
If Mitigated
No impact if SSH plugin is disabled or proper input validation is implemented.
🎯 Exploit Status
Exploitation requires access to SSH functionality; likely requires some user interaction or existing access.
