DO NOT PUBLISH SECURITY REPORTS PUBLICLY.

If you find an issue that might have security implications, send a report to security[at]symfony.com.

The full security reporting and resolution process is described in the Symfony documentation.

Twig treats template source as trusted code unless the template is rendered in the Twig sandbox. The regular Twig environment is not a security boundary.

Applications that render templates supplied by untrusted users must enable and correctly configure the Twig sandbox. Any behavior that is possible because an application renders an untrusted template without the sandbox is not a security issue in Twig and must not be reported as one.

Reports about untrusted templates are in scope only when they demonstrate a sandbox restriction bypass while the sandbox is enabled and its security policy does not allow the demonstrated operation.
