## Overview

### Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-xjw5-q542-3vmr. This link is maintained to preserve external references.

### Original Description
Grav before 2.0.16 contains an incomplete default denylist in the Twig sandbox configuration that fails to block access to system configuration secrets. Attackers with page-edit permission can use config.get() or config.toArray() in Twig templates to retrieve sensitive values like system.cache.redis.password when config_access is enabled.

## Affected packages

- `getgrav/grav < 2.0.16`

## Remediation

Refer to the advisory for the patched release.
