Summary

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-4v9q-p283-qc2m. This link is maintained to preserve external references. ### Original Description Grav before 2.0.15 contains a path traversal vulnerability in the static asset server within index.php that uses string prefix matching instead of directory-boundary validation. Unauthenticated attackers can access files in sibling directories by exploiting directory names that extend the base path string, such as requesting assets-secret when assets is the configured base.
