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