# Enforce oauth state parameter validation

Configure the **glide.oauth.state.parameter.required** property to prevent your instance from cross-site request forgery \(CSRF\) attacks.

The **glide.oauth.state.parameter.required** system property enables the **State** parameter to be required in an OAuth request for authorization code flow. Beginning in the Madrid release, the system property **glide.oauth.state.parameter.required** adds a **State** parameter for an OAuth request. For zbooted instances, the property is **true**. For upgraded instances, the property is not present, so the **State** parameter is not enabled. The **State** parameter is a string value, and should not contain special characters. The State parameter cannot be empty or " ". Not setting the **State** parameter to **true** ensures that an attacker cannot perform CSRF attacks during authentication can allow an attacker to perform operations as the victim.

Ensure that the property **glide.oauth.state.parameter.required** is set to **true**.
