CVE-2026-92466
zlt2000 microservices-platform through 6.0.0 contains a missing authorization vulnerability where the zlt.security.auth.urlPermission.enable flag defaults to false, disabling all permission checks after authentication. Authenticated users with no roles can access administrative APIs including user management, role assignment, and Elasticsearch index operations by bypassing the disabled authorization enforcement.
