Prior to 3.4.1.15, a Data Reader admin_user on a TDengine Cloud DB instance could run create udf even though standard users should have read-only permissions for non-database objects and show dnodes and create user were denied. This issue is fixed in version 3.4.1.15."

Antes de la versión 3.4.1.15, un admin_user de Lector de Datos en una instancia de DB en la nube de TDengine podía ejecutar create udf a pesar de que los usuarios estándar deberían tener permisos de solo lectura para objetos que no son de la base de datos y show dnodes y create user estaban denegados. Este problema se ha corregido en la versión 3.4.1.15."
