CVE-2026-92681
CriticalCVSS 9.3Summary
In @neo4j/graphql versions up to and including 7.6.3, @authentication directives applied at the schema level or on Query or Mutation types are silently ignored for top-level fields annotated with @cypher. Only @authentication directives placed directly on individual fields are enforced. An application exposing a top-level @cypher field and relying on schema-level or type-level @authentication allows unauthenticated callers to invoke the field and run the configured Cypher statement with the privileges of the GraphQL service account, potentially permitting reading and modifying data. Fixed in 7.6.4.
Risk Assessment
Unauthenticated users may invoke protected fields and perform data operations with the privileges of the service account. This may lead to unauthorized data disclosure or modification.
Recommendation
Update @neo4j/graphql to version 7.6.4 or later. Additionally, verify that @authentication directives are placed directly on @cypher fields and audit the GraphQL service account's privileges.
Other vulnerabilities in @neo4j/graphql
See all- CVE-2026-92682High
In @neo4j/graphql versions from 7.0.0 up to but not including 7.6.4, the none quantifier in @authorization filters on relationships and connections is not negated when translated to Cypher, so it behaves like some. A rule such as "none of the related denied users matches the JWT subject" therefore returns exactly the records it was meant to exclude, and excludes those it was meant to return. An authenticated user whom such a rule is meant to deny can read the protected records. This is also the case for mutations, so the impact is that sensitive data could also be created and deleted by users that shouldn't have access according to the typedefs. Fixed in 7.6.4.
- CVE-2026-19869High
@neo4j/graphql from version 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. The field-level rule is silently discarded, allowing any client satisfying the coarser type-level requirement to invoke the more-restricted field.
- CVE-2026-5423High
The @neo4j/graphql library versions prior to 7.5.6 fail to verify the authenticity of a client-supplied, pre-decoded JWT object passed through GraphQL subscription connectionParams. As a result, any unauthenticated remote client can forge arbitrary JWT claims (e.g., sub, roles) in connectionParams.jwt and have them accepted as authenticated identity for @authentication and @subscriptionsAuthorization directive evaluation. This allows an unauthenticated attacker to receive subscription events restricted to specific authenticated roles/users. Upgrade to versions 7.5.6+ or 5.12.14+.
Original NVD description (English source)
In @neo4j/graphql versions up to and including 7.6.3, @authentication directives applied at the schema level or on the Query or Mutation types are silently ignored for top-level fields annotated with @cypher. Only @authentication directives placed directly on the individual fields are enforced. An application that exposes a top-level @cypher field and relies on schema-level or type-level @authentication to protect it allows unauthenticated callers to invoke the field and run the configured Cypher statement with the privileges of the GraphQL service account, which may permit reading and modifying data. Fixed in 7.6.4.
