CVE-2025-31485 Information

Description

API Platform Core is a system to create hypermedia-driven REST and GraphQL APIs. Prior to 4.0.22 a GraphQL grant on a property might be cached with different objects. The ApiPlatform\GraphQl\Serializer\ItemNormalizer::isCacheKeySafe() method is meant to prevent the caching but the parent::normalize method that is called afterwards still creates the cache key and causes the issue. This vulnerability is fixed in 4.0.22.
