AI-suggested

Upgrade Grav to version 2.0.14 or later, where this vulnerability is fixed. Since the advisory is a duplicate and withdrawn, refer to the original advisory GHSA-xhfv-7758-r9hx for official patch details and remediation instructions.

Description

Grav CMS versions before 2.0.14 contain a critical vulnerability where the core group blueprint's access field lacks proper admin.super guard. This allows a delegated admin.users operator to escalate privileges to super-admin by setting access[admin][super]=true, thereby gaining high-level capabilities such as scheduler and Twig evaluation.
