-Hugo will soon introduce a concept of _Content Source Plugins_ (AKA _Pages from Data_), but the above will still hold true.

+## Security Policy
+
+{{< new-in "0.91.0" >}}
+
+Hugo has a built-in security policy that restricts access to [os/exec](https://pkg.go.dev/os/exec), remote communication and similar.
+
+The default configuration is listed below. And build using features not whitelisted in the security policy will faill with a detailed message about what needs to be done. Most of these settings are whitelists (string or slice, [Regular Expressions](https://pkg.go.dev/regexp) or `none` which matches nothing).
+
+{{< code-toggle config="security" />}}
+
+Note that these and other config settings in Hugo can be overridden by the OS environment. If you want to block all remote HTTP fetching of data:
+
+```
+HUGO_SECURITY_HTTP_URLS=none hugo 
+```
