AI-suggested

To mitigate this vulnerability, organizations should upgrade Neo4j Enterprise Edition to version 2026.02 or 5.26.22 where the issue is resolved. Until upgrading, administrators must carefully review and avoid configurations that combine multiple OIDC providers with mixed roles (authorization and authentication-only) to prevent unintended privilege grants. Specifically, avoid assigning higher privilege groups to authentication-only providers or ensure that authentication-only providers do not contain groups with elevated privileges. Conduct thorough audits of OIDC provider configurations and group privilege assignments. Implement strict role-based access controls and monitor authentication and authorization logs for anomalies. Additionally, restrict administrative access to Neo4j configuration settings to trusted personnel only. Employ defense-in-depth by isolating Neo4j instances and limiting network access to trusted users and systems.

Description

An edgecase in SSO implementation in Neo4j Enterprise edition versions prior to version 2026.02 can lead to unauthorised access under the following conditions: If a neo4j admin configures two or more OIDC providers AND configures one or more of them to be an authorization provider AND configures one or more of them to be authentication-only, then those that are authentication-only will also provide authorization. This edgecase becomes a security problem only if the authentication-only provider contains groups which have higher privileges than provided by the intended (configured) authorization provider. When using multiple plugins for authentication and authorisation, prior to the fix the issue could lead to a plugin configured to provide only authentication or authorisation capabilities erroneously providing both capabilities. We recommend upgrading to versions 2026.02 (or 5.26.22) where the issue is fixed.
