Details
As written in the advisory (Markdown source, shown as plain text).
# 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](https://github.com/github-community-projects/graphql-client) to load external schemas via GraphQL introspection.
