### Description 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). ### Resolution The patch ensures that the sandbox security checks are always run at runtime. ### Credits We would like to thank Fabien Potencier for reporting and fixing the issue.
