9.8 · CRITICALOverview
CVE-2026-1524 is a critical-severity vulnerability affecting neo4j neo4j. It was published on March 11, 2026 and has a CVSS 3.1 base score of 9.8 (CRITICAL).
This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from neo4j. Update neo4j to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
