CORS allows resources to access function apps

Description

Cross-Origin Resource Sharing (CORS) should not allow all domains to access your Function app. Allow only required domains to interact with your Function app.

Code Example

resource "azurerm_function_app" "example" {
                ...
                site_config {
+                 cors {
+                     allowed_origins = ["192.0.0.1"]
                  }
                }
              }
