# Enforce Query ACLs for SubLists, List Counts and Widget Data Tables

Enforce query ACLs on sublist, list count, and widget data table queries using system properties.

Set **com.glide.security.query\_acl.enabled.sub\_lists** to **true** to enforce query ACLs on sublist queries, such as grouped lists and related lists.

Set **com.glide.security.query\_acl.enabled.list\_count** to **true** to enforce query ACLs on list count queries.

Set **glide.security.query\_acl.enabled.data\_table** to **true** to enforce query ACLs on widget data tables.

If any of these system properties are set to **false**, an attacker can use blind queries to enumerate and exfiltrate data due to the default behavior of `GlideRecord.addEncodedQuery`. If these properties don't exist in the System Properties \[sys\_properties\] table, the secure default of true is used. A third option, **external\_and\_guests**, enforces ACLs only for external users and guests.

Ensure these system properties do not appear in the System Properties \[sys\_properties\] table or are set to **true**.

Security risk

</td><td>

-   Severity score: 5.3
-   CVSS score: Medium
-   Security Risk: ACLs can be bypassed disclosing field data to users who do not have permissions to see it. This could include sensitive data depending on the table exploited.
