-------- 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.

Multiple File Upload [4] module, there is nothing you need to do.

-------- SOLUTION
------------------------------------------------------------

  * If you use the Webform Multiple File Upload module for Drupal 7.x,
