# About DVGA



Damn Vulnerable GraphQL is a deliberately weak and insecure implementation of GraphQL that provides a safe environment to attack a GraphQL application, allowing developers and IT professionals to test for vulnerabilities.



## DVGA Operation Support



- Queries

- Mutations

- Subscriptions



DVGA has numerous flaws, such as Injections, Code Executions, Bypasses, Denial of Service, and more. See the full list under the [Scenarios](#scenarios) section. A public [Postman collection](https://www.postman.com/devrel/workspace/ab3d0551-b65d-4588-b464-1a317e8d7e98/collection/14270212-b5875c90-d36e-43f4-8bd7-2c81b556245d?action=share&creator=14270212) is also available to replay solutions to the challenges. You can import the collection by clicking on the Run in Postman button below.

# Installation



## Docker



### Clone the repository



`git clone https://github.com/dolevf/Damn-Vulnerable-GraphQL-Application.git && cd Damn-Vulnerable-GraphQL-Application`



### Build the Docker image



`docker build -t dvga .`



**Note:** If you are using an ARM-based Mac, use the dedicated Dockerfile.arm64 file:



`docker build -t dvga -f Dockerfile.arm64 .`



### Create a container from the image



`docker run -d -t -p 5013:5013 -e WEB_HOST=0.0.0.0 --name dvga dvga`



In your browser, navigate to http://localhost:5013



Note: if you need the application to bind on a specific port (e.g. 8080), use **-e WEB_PORT=8080**.



## Docker Registry



### Pull the docker image from Docker Hub



`docker pull dolevf/dvga`



Docker Hub image: [dolevf/dvga](https://hub.docker.com/r/dolevf/dvga)



### Create a container from the image

In your browser, navigate to http://localhost:5013



## Server



**Note**: Python 3.10 is **not supported** yet!



### Navigate to /opt



`cd /opt/`



### Clone the repository



`git clone [email protected]:dolevf/Damn-Vulnerable-GraphQL-Application.git && cd Damn-Vulnerable-GraphQL-Application`



### Install Requirements



`pip3 install -r requirements.txt`



### Run application



`python3 app.py`



In your browser, navigate to http://localhost:5013.
