Source Code for "LLMxCPG: Context-Aware Vulnerability Detection Through Code Property Graph-Guided Large Language Models"

This repository contains the source code for "LLMxCPG: Context-Aware Vulnerability Detection Through Code Property Graph-Guided Large Language Models" accepted at Usenix Security 2025, a framework for vulnerability detection using Code Property Graphs (CPG) and Large Language Models (LLM).

The core methodology involves a two-phase process:

1. Slice Construction: An LLM generates specific queries for a Code Property Graph to extract a minimal, relevant "slice" of code that may contain a vulnerability.

2. Vulnerability Detection: A second LLM analyzes the extracted code slice to classify it as either vulnerable or safe.
