CVE-2026-1497

Incorrect resolving of namespaces in composite databases in Neo4j Enterprise edition prior to versions 2026.02 and 5.26.22 can lead to the following scenario: an admin that intends to give a user an access to a remote database constituent "namespace.name" will inadvertently grant access to any local database or remote alias called "name". If such database or alias doesn't exist when the command is run, the privileges will apply if it's created in the future.

Summary		(es) La resolución incorrecta de espacios de nombres en bases de datos compuestas en Neo4j Enterprise edition anterior a las versiones 2026.02 y 5.26.22 puede llevar al siguiente escenario: un administrador que intenta dar a un usuario acceso a un constituyente de base de datos remoto 'namespace.name' concederá acceso inadvertidamente a cualquier base de datos local o alias remoto llamado 'name'. Si dicha base de datos o alias no existe cuando se ejecuta el comando, los privilegios se aplicarán si se crea en el futuro.
