Description

Remote code execution when loading a crafted GraphQL schema (CVE-2025-27407)

Details

graphql-ruby is a Ruby implementation of GraphQL. Starting in version 1.11.5 and prior to versions 1.11.8, 1.12.25, 1.13.24, 2.0.32, 2.1.14, 2.2.17, and 2.3.21, 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. Versions 1.11.8, 1.12.25, 1.13.24, 2.0.32, 2.1.14, 2.2.17, and 2.3.21 contain a patch for the issue.

Reason for inclusion in AVID: CVE-2025-27407 describes remote code execution in graphql-ruby when loading crafted GraphQL schemas. graphql-ruby is a library used in AI service stacks and model-serving infrastructures, and this vulnerability could affect the software supply chain of general-purpose AI systems that rely on GraphQL APIs or schema loading from untrusted sources. The CVE provides explicit vulnerable versions, the affected functionality, and patches, indicating a concrete security risk (RCE) with clear evidence.
