+title: graphql allows remote code execution when loading a crafted GraphQL schema
+date: 2025-03-12
+description: |
+  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.
