# Configure Service Portal Widgets Allow List

Learn how to configure the glide.service\_portal.widget.allow\_list property securely so that the access control lists \(ACLs\) for the tables do not expose sensitive information.

The **glide.service\_portal.widget.allow\_list** system property determines the list of widgets that are allowed to attempt to access any table on the instance. ACLs for those tables will still be enforced. If there are misconfigured empty ACLs on tables on the instance, widgets in this list may allow access to those tables, leading to information disclosure. This property is only enforced if the widget makes use of SNCACLWidgetUtil, and the property **glide.service\_portal.widget.enforce\_public\_check** is set to '**true**.

Ensure that the **glide.service\_portal.widget.allow\_list** system property has an empty value empty or does not exist.
