Name of the Vulnerable Software and Affected Versions Grav CMS versions prior to 1.3.0

Description A cross-site scripting (XSS) issue allows remote attackers to inject arbitrary web script or HTML via the PATH INFO to the "admin/tools" endpoint. This is due to a vulnerability in the system/src/Grav/Common/Twig/Twig.php file.

Recommendations For Grav CMS versions prior to 1.3.0, update to version 1.3.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the "admin/tools" endpoint until a patch is available. Avoid using the PATH INFO to inject arbitrary data into the admin/tools endpoint until the issue is resolved.
