--- upgrade: - | After this upgrade, users will no longer be able use network resources they cannot see or "show" on load balancers. Operators can revert this behavior by setting the "allow_invisible_reourece_usage" configuration file setting to ``True``. security: - | Previously, if a user knew or could guess the UUID for a network resource, they could use that UUID to create load balancer resources using that UUID. Now the user must have permission to see or "show" the resource before it can be used with a load balancer. This will be the new default, but operators can disable this behavior via the setting the configuration file setting "allow_invisible_resource_usage" to ``True``. This issue falls under the "Class C1" security issue as the user would require a valid UUID.
