## Overview

### Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-xhfv-7758-r9hx. This link is maintained to preserve external references.

### Original Description
Grav before 2.0.14 fails to guard the access field in the core group blueprint with the required security@: admin.super restriction. A delegated admin.users operator can save a group with access[admin][super]=true to escalate to super-admin, gaining scheduler and Twig evaluation capabilities.

## Affected packages

- `getgrav/grav < 2.0.14`

## Remediation

Refer to the advisory for the patched release.
