Name of the Vulnerable Software and Affected Versions Neo4j Enterprise edition versions prior to 2026.02 Neo4j Enterprise edition versions prior to 5.26.22

Description An issue in the Single Sign-On (SSO) implementation in Neo4j Enterprise edition can lead to unauthorized access. This occurs when a Neo4j administrator configures two or more OpenID Connect (OIDC) providers, with at least one configured for authorization and one configured for authentication only. If the authentication-only provider contains groups with higher privileges than the intended authorization provider, it can incorrectly provide authorization capabilities. Prior to the fix, a plugin configured for only authentication or authorization could erroneously provide both capabilities.

Recommendations Upgrade to version 2026.02. Upgrade to version 5.26.22.
