💻 Code & Dataset: GitHub Repository

🎯 What it does

Feed the model a raw CVE description, CVSS score, and vendor, and it will generate a comprehensive report including:

Executive Summary (Plain English explanation)
Technical Analysis (Vectors, complexity, privileges)
Indicators of Compromise (IOCs)
MITRE ATT&CK Mappings
Risk Assessment
Remediation Steps
Detection Rules (YARA/Sigma)
