name: GraphQL Alias-based Batching
author: Dolev Farhi

description: |
GraphQL supports aliasing of multiple sub-queries into a single queries. This allows users to request multiple objects or multiple instances of objects efficiently.
However, an attacker can leverage this feature to evade many security measures, including rate limit.

Limit queries aliasing in your GraphQL Engine to ensure mitigation of aliasing-based attacks.

name: GraphQL Field Suggestion Information Disclosure
author: Dolev Farhi
severity: info
description: |
If introspection is disabled on your target, Field Suggestion can allow users to still earn information on the GraphQL schema.
By default, GraphQL backends have a feature for fields and operations suggestions.
If you try to query a field but you have made a typo, GraphQL will attempt to suggest fields that are similar to the initial attempt.

info:
name: GraphQL CSRF / GET method
author: Dolev Farhi
severity: info
description: |
Cross Site Request Forgery happens when an external website gains ability to make API calls impersonating an user if he visits the website while being authenticated to your API.
Allowing API calls through GET requests can lead to CSRF attacks, because cookies are added automatically to GET requests by the browser.
