# Enforce Query ACLs for Knowledge Quick Links

Enforce query ACLs for Knowledge Quick Links using a system property.

When the **com.glide.security.query\_acl.enabled.knowledge\_quick\_links** system property is set to **true**, query ACLs are enforced for Knowledge Quick Links. If this property is set to **false**, an attacker can use blind queries to enumerate and exfiltrate data due to the default behavior of `GlideRecord.addEncodedQuery`.

If the property doesn’t exist in the System properties \[sys\_properties\] table, the secure default of **true** is used. A third option, **external\_and\_guests** enforces query ACLs only for external users and guests.

Verify that the **com.glide.security.query\_acl.enabled.knowledge\_quick\_links** system property is 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 don’t have permissions to see it. This disclosure could include sensitive data depending on the table exploited.
