   * Vulnerability: Access bypass

-------- DESCRIPTION
---------------------------------------------------------

This module enables you to upload multiple files at once in a webform.
The module doesn't sufficiently check access to file deletion urls.
This vulnerability is mitigated by the fact that an attacker must have a role
with the permission to edit all or their own webform submissions.

-------- SOLUTION
