Hello guys! 📨🧑‍💻

I'm Cyber Security Researcher from Myanmar. ​Today, I'm excited to share a new tool specifically designed for Web Security Researchers and Bug Hunters. It targets a common yet critical issue: GraphQL Misconfigurations.

​I developed this Python Automation Tool to easily detect High-Risk Database Information Disclosure vulnerabilities by leveraging GraphQL Introspection.

​​🔍 Why did I decide to publish this tool? ​I first discovered the impact of this specific bug around January 2026. At that time, I found that this vulnerability affected over 3.4k global domains. I have personally reported it to about half of them and successfully collected several bounties.

None

​Note: Since I am still active in reporting these, I won't be sharing the Shodan dorks or giving them out via DM. 🫡

​Originally, I submitted this to the vendor to claim a CVE. However, because it's a misconfiguration bug used within an exploit chain, they decided not to assign a CVE. ​Instead of letting the research go to waste, I thought: "If I can't get a CVE, at least my fellow hunters can find this tool useful." So, I decided to go public.

​⚙️ How it works & Features ​Using the tool is straightforward. You just need the domain and the GraphQL endpoint. ​Command: $ python3 ginja.py [domain] [endpoint]

The user interface of this tool is like following:

None

💻 ​Key Features: ​User-Friendly: Just input the target domain and the GraphQL API route. ​Flexible Testing: You can test for Unauthorized Access (No Token) or provide an existing Auth Token/Authorization Header for deeper testing. ​Full Automation: No more manual schema hunting. The tool automatically checks if GraphQL schemas are leaking sensitive database information.

​🚨 The Vulnerability: Why Introspection Matters? ​This tool works specifically on APIs where GraphQL Introspection is enabled. In a production environment, leaving Introspection enabled is a significant misconfiguration. It allows attackers to query the system for information about its internal schema, effectively handing them a map of your entire database structure.

​💻 Installation ​You can find the source code and installation guide here: 🔗 GitHub: https://github.com/m00nisSmiling/ginja
