Description

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-3jhr-mxmx-38cx. This link is maintained to preserve external references. ### Original Description Grav before 2.0.16 allows sandboxed Twig templates to access sensitive User fields through allow-listed offsetGet() and offsetexists() methods that lack field filtering. Attackers with page-edit permissions can call offsetGet() on User objects to extract hashed passwords and 2FA secrets, enabling offline password cracking and authentication bypass.
