CVE-2026-1497 Neo4j CVE debrief

Who should care

Administrators of Neo4j Enterprise databases, users with access to composite databases, and security teams responsible for vulnerability management should be aware of this issue. They should verify user access controls, review database constituents, and ensure proper configuration of remote database constituents to prevent unintended access grants.

Technical summary

Incorrect resolving of namespaces in composite databases in Neo4j Enterprise edition prior to versions 2026.02 and 5.26.22 can lead to unintended access grants. An admin intending to give a user access to a remote database constituent 'namespace.name' may inadvertently grant access to any local database or remote alias called 'name'. This issue arises because the system does not properly resolve namespaces, potentially allowing access to unintended databases or aliases. Administrators should verify user access controls and review database constituents for potential namespace resolution issues.

Defensive priority

Administrators of Neo4j Enterprise databases should verify user access controls and review database constituents for potential namespace resolution issues.
