Summary
graphql allows remote code execution when loading a crafted GraphQL schema
Details

Summary

Loading a malicious schema definition in GraphQL::Schema.from_introspection (or GraphQL::Schema::Loader.load) can result in remote code execution. Any system which loads a schema by JSON from an untrusted source is vulnerable, including those that use GraphQL::Client to load external schemas via GraphQL introspection.

Severity
