Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Neo4j GraphQL Library是美国Neo4j公司的一个将图数据模型暴露为GraphQL接口的库。 Neo4j GraphQL Library 5.2.0版本至5.12.15之前版本、6.0.0版本至6.6.4版本和7.0.0版本至7.6.0之前版本存在授权问题漏洞，该漏洞源于当同一操作类型上存在类型级@authentication规则时，字段级@authentication规则未被强制执行，导致满足类型级要求的客户端可调用更严格限制的字段，存在未授权访问风险。

Vulnerability Title
Privilege Escalation via Dropped Field-Level @authentication
Source: CVE Program / CVE List V5
Vulnerability Description
@neo4j/graphql from 5.2.0 until the patched versions fails to enforce field-level @authentication rules on root custom-resolver fields when a type-level @authentication rule is also present on the same operation type. When both a type-level @authentication (on Query/Mutation) and a field-level @authentication (on a root custom-resolver field within that type) are declared, only the type-level rule is evaluated and the field-level rule is silently discarded. As a result a stricter per-field requirement — such as an admin-role JWT claim (jwt: { roles_INCLUDES: "admin" }) — is never checked, and any client that satisfies the coarser type-level requirement can invoke the more-restricted field. No token forgery is involved: a legitimately issued, correctly signed non-admin token (e.g. roles: ["user"]) is sufficient.
