GraphQL Playground Module

What is the "GraphQL Playground?"

The GraphQL Playground module is designed to detect misconfigurations in GraphQL Playground instances. GraphQL Playground is an interactive development environment for GraphQL APIs. It allows developers to explore and test GraphQL queries, mutations, and subscriptions. This module focuses on identifying potential misconfigurations in the GraphQL Playground setup.

This module has an informative severity level, which means it provides valuable information but does not indicate a critical vulnerability or security issue.

Impact

If misconfigurations are detected in the GraphQL Playground instance, it could potentially expose sensitive information or allow unauthorized access to the API. This can lead to data breaches or unauthorized actions on the affected system.

How the module works?

The GraphQL Playground module works by sending HTTP requests to the target system and analyzing the responses based on predefined matching conditions. It checks for the presence of specific HTML elements, such as the "<title>GraphQL playground</title>" tag, in the response body. Additionally, it verifies that the response header contains the content type "text/html" and the HTTP status code is "200".

By evaluating these conditions, the module can determine if the target system is running a GraphQL Playground instance and whether it is properly configured.

Here is an example of an HTTP request that the module may send:

GET /graphql HTTP/1.1
Host: example.com
User-Agent: Vidoc
Accept: */*

The module's matching conditions are as follows:

- The response body must contain the "<title>GraphQL playground</title>" tag. - The response header must have the content type "text/html". - The HTTP status code must be "200".

If all these conditions are met, the module will report a potential misconfiguration in the GraphQL Playground instance.
