Package : ruby-graphql
Version : 1.11.12-0+deb11u1
CVE ID : CVE-2025-27407
Debian Bug : 1100442

ruby-graphql is GraphQL language and runtime for Ruby. It was
discovered that 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.

For Debian 11 bullseye, this problem has been fixed in version
1.11.12-0+deb11u1.

We recommend that you upgrade your ruby-graphql packages.
