# CVE-2026-92684: Aggregation queries can bypass authentication restrictions in @neo4j/graphql

Status: published. Published: 2026-11-10. Updated: 2026-11-10.

Missing Authentication for Critical Function in aggregation queries in Neo4j @neo4j/graphql 5.0.0 before 5.12.17 and 7.0.0 before 7.6.8 allows remote attackers to read protected data via GraphQL aggregation queries. Field-level @authentication is not enforced on string aggregates, which can return stored values verbatim, and connection-root aggregates bypass an entity's AGGREGATE authentication requirement, allowing unauthenticated callers to obtain aggregate results.

## Remediation

- fix: Upgrade @neo4j/graphql to 7.6.8 (latest) or 5.12.17 (LTS). (source: CNA: Neo4j)
- workaround: Restrict access to aggregate queries over protected data until the upgrade is applied. (source: CNA: Neo4j)
