This module provides an API for adding universally unique identifiers (UUID) to Drupal objects, most notably entities.
The module module has an arbitrary file upload vulnerability when it's used in combination with the services REST server.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission to allow to upload to the file create REST endpoint.
