CVE-2021-41249 Information

Description

GraphQL Playground is a GraphQL IDE for development of graphQL focused applications. All versions of graphql-playground-react older than graphql-playground-react@1.7.28 are vulnerable to compromised HTTP schema introspection responses or schema prop values with malicious GraphQL type names exposing a dynamic XSS attack surface that can allow code injection on operation autocomplete. In order for the attack to take place the user must load a malicious schema in graphql-playground. There are several ways this can occur including by specifying the URL to a malicious schema in the endpoint query parameter. If a user clicks on a link to a GraphQL Playground installation that specifies a malicious server arbitrary JavaScript can run in the user’s browser which can be used to exfiltrate user credentials or other harmful goals. If you are using graphql-playground-react directly in your client app upgrade to version 1.7.28 or later.
