   * Advisory ID: DRUPAL-SA-CONTRIB-2016-059
   * Project: D8 Editor File upload [1]     (third-party module)
   * Version: 8.x
   * Date: 2016-November-02
   * Security risk: 12/25 ( Moderately Critical)
     AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
   * Vulnerability:

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

This module enables you to upload files directly within the CKEditor and
create a link to download the given file.

The module doesn't sufficiently check the uploaded file extensions when the
allowed extensions list is not the default one.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission to use a text filter that enables this CKEditor plugin
and does not use the default allowed extensions.


-------- CVE IDENTIFIER(S) ISSUED
--------------------------------------------

   * /A CVE identifier [3] will be requested, and added upon issuance, in
     accordance with Drupal Security Team processes./

-------- VERSIONS AFFECTED
---------------------------------------------------

   * D8 Editor File Upload 8.x-1.x versions prior to 8.x-1.2.

Drupal core is not affected. If you do not use the contributed D8 Editor File
upload [4] module, there is nothing you need to do.

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

Install the latest version:

   * If you use the D8 Editor File Upload module for Drupal 8.x, upgrade to D8
     Editor File Upload 8.x-1.2 [5]

Also see the D8 Editor File upload [6] project page.
