CVE-2024-45411: Twig has a possible sandbox bypass

Under some circumstances, the sandbox security checks are not run which allows user-contributed templates to bypass the sandbox restrictions.

The security issue happens when all these conditions are met:

• The sandbox is disabled globally;
• The sandbox is enabled via a sandboxed include() function which references a template name (like included.twig) and not a Template or TemplateWrapper instance;
• The included template has been loaded before the include() call but in a non-sandbox context (possible as the sandbox has been globally disabled).
