Description
Grav is a file-based Web platform. Prior to 2.0.2, the Grav Twig content sandbox permits grav.offsetGet('config') to return the raw configuration object and permits json_encode, print_r, yaml_encode, and string filters to serialize that object without passing through GravSecurityPolicy::checkMethodAllowed. A user with page-author permissions can render sandboxed content that exposes plugins.* configuration secrets, including SMTP credentials, API keys, and plugin database credentials. This issue is fixed in version 2.0.2.
