Description

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This advisory has been withdrawn because it is a duplicate of GHSA-xjw5-q542-3vmr.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.

Weakness

CWE-522: Insufficiently Protected Credentials

The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.

How to prevent it
  • Architecture and Design: Use an appropriate security mechanism to protect the credentials.
  • Architecture and Design: Make appropriate use of cryptography to protect the credentials.
  • Implementation: Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
