CVE-2025-31485Network attack vector

Unauthorized property disclosure via cross-object cache reuse

Published Apr 3, 2025 · Updated Apr 8, 2025

Information disclosure in API Platform Core before 3.4.17 and 4.0.0-alpha.1 through 4.0.21 allows remote attackers to read secured GraphQL properties. ItemNormalizer leaves the cache key unset when property security is object-dependent, but parent::normalize then creates and reuses a key across different objects instead of reevaluating each grant. Exposure requires a GraphQL property with an object-dependent security expression and normalization of differently authorized objects; the reported consequence is disclosure only.
