Descriptions

In the Query Engine in Couchbase Server 6.5.x and 6.6.x through 6.6.1, Common Table Expression queries were not correctly checking the user's permissions, allowing read-access to resources beyond what those users were explicitly allowed to access.

En el Motor de Consulta en Couchbase Server versiones 6.5.x y versiones 6.6.x hasta 6.6.1, las consultas de Common Table Expression no comprobaban correctamente los permisos del usuario, permitiendo un acceso de lectura a recursos más allá de lo que esos usuarios tenían explícitamente permitido acceder
