KunLun-M

KunLun-M（昆仑镜） is an open-source static code security analysis system. It builds an AST graph from source code and performs taint analysis to detect vulnerabilities.

• 14 languages: PHP / JavaScript / TypeScript / Python / Java / Go / Ruby / Rust / C / C++ / C# / Kotlin / Lua / Solidity
• AST graph engine: Builds a full program graph (call graph, data flow, AST structure) for taint tracking
• CLI / Console / Web three modes
• Built-in AI Agent skill: One-click integration with Codex / Claude Code / Hermes etc.

Quick Start

# Install
git clone https://github.com/LoRexxar/Kunlun-M.git && cd Kunlun-M
pip install -r requirements.txt
cp Kunlun_M/settings.py.bak Kunlun_M/settings.py

# Init database
python kunlun.py init

# Scan
python kunlun.py scan -t /path/to/project

# Scan with specific language
python kunlun.py scan -t /path/to/project -lan php

# Export HTML report
python kunlun.py scan -t /path/to/project -f html -o report.html

# Web dashboard
python kunlun.py web -p 9999

CLI Commands

python kunlun.py  [args]

Core Commands

Scan Parameters

Other Commands

Console Mode

Console mode provides an interactive REPL with graph traversal support:

python kunlun.py console

KunLun-M> scan
KunLun-M(scan)> set target /path/to/project
KunLun-M(scan)> run

KunLun-M> load 42
KunLun-M(result)> show vuls
KunLun-M(result)> graph           # Enter graph traversal REPL
>>> g.function.main.ownout.count
14

Graph Traversal REPL

Inside the graph REPL, use g as the entry point for Joern-style graph queries:

>>> g.function                          # All function nodes
>>> g.file.index                        # File named 'index'
>>> g.identifier.session.dfg            # Data flow from 'session'
>>> g.function.main.ownout              # AST children of main
>>> g.identifier.input.uses             # Functions using 'input'
>>> g.function.exec.shortest_path      # Shortest path to 'exec'

See docs/graph-traversal.md for the full API reference.

Web Dashboard

python kunlun.py web -p 9999

Web mode includes:

• Dashboard: Task management, project overview, scan results
• Graph Analysis: Interactive Cytoscape.js graph visualization (4 layouts)
• API: Token-authenticated REST API for automation

Data Export & Import

Project Archive

Export a complete project (database records + graph files) as a portable .tar.gz:

python kunlun.py export-project -p nodejs
python kunlun.py import-project -f kunlun-export-nodejs-*.tar.gz [--force]

Neo4j Graph Export

Export AST graphs to Neo4j for advanced Cypher queries:

python kunlun.py export-neo4j -p nodejs --clean
python kunlun.py export-neo4j -s 42 --neo4j-uri bolt://host:7687

See docs/data-export.md for full documentation.

AI Agent Integration

If you’re using an AI Agent (Codex / Claude Code / Hermes etc.), send:

Download https://github.com/LoRexxar/Kunlun-M.git and load its skill (kunlun-m-general).

The agent will auto-detect skills/kunlun-m-general/ and follow the docs to initialize and scan.

See docs/skill_kunlunm_general.md for scripted workflows.

Supported Languages

Plugins

PHP Deserialization Chain Finder

Automatically discovers PHP deserialization chains and generates PoC files:

python kunlun.py plugin php_unserialize_chain_tools -t /path/to/php/project

Entrance Finder

Quickly finds potential PHP entry pages in large codebases:

python kunlun.py plugin entrance_finder -t /path/to/php/project -l 3

Development

Rule Development

Rules follow the convention rules/{language}/CVI_{id}.py. See rules/rule.template for a template.
