CVE-2025-31481
GraphQL query operations security can be bypassed
Description
### Summary Using the Relay special `node` type you can bypass the configured security on an operation. ### Details Here is an example of how to apply security configurations for the GraphQL operations: ```php #[ApiResource( security: "is_granted('ROLE_USER')", operations: [ /* ... */ ], graphQlOperations: [ new Query(security: "is_granted('ROLE_USER')"), //... ], )] class Book { /* ... */ } ``` This indeed checks `is_granted('ROLE_USER')` as expected for a GraphQL query like the following: ```php query { book(id: "/books/1") { title } } ``` But the security check can be bypassed by using the `node` field (that is available by default) on the root query type like that: ```php query { node(id: "/books/1") { ... on Book { title } } } ``` This does not execute any security checks and can therefore be used to access any entity without restrictions by everyone that has access to the API. ### Impact Everyone using GraphQl with the `security` attribute. Not sure whereas this works with custom resolvers nor if this also applies on mutation. Patched at https://github.com/api-platform/core/commit/60747cc8c2fb855798c923b5537888f8d0969568
