CyberRota Analysis
AI-GeneratedGrav versions prior to 2.0.2 are vulnerable to a Twig sandbox bypass that allows users with page author privileges to access sensitive configuration secrets, including SMTP credentials and API keys. The vulnerability arises from the ability to exploit allow-listed methods to serialize the full configuration object, bypassing intended security measures. Administrators and developers using affected versions should prioritize applying the update to mitigate the risk of sensitive data exposure.

Original NVD Description
Grav before 2.0.2 contains a Twig sandbox bypass that allows a page author (any admin.pages user, or anyone able to write to user/pages) to exfiltrate configuration secrets. Although the sandbox replaces the 'config' variable with a redacted facade and strips Config::get/toArray from the method allowlist, the raw container remains accessible via the allow-listed grav.offsetGet('config'), which returns the real Config object. Allow-listed object-dumping filters (json_encode, print_r, yaml_encode) then serialize that object at the PHP level without invoking the sandbox method gate, exposing the full config tree including plugin secrets such as SMTP credentials, API keys, and plugin DB credentials. This is an incomplete fix for GHSA-j274-39qw-32c9.
