  * Advisory ID: DRUPAL-SA-CONTRIB-2016-053
  * Project: Webform [1]     (third-party module)
  * Version: 7.x
  * Date: 2016-October-19
  * Security risk: 9/25 ( Less Critical)
    AC:Basic/A:None/CI:None/II:None/E:Theoretical/TD:Default [2]
  * Vulnerability: Access bypass

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

This module provides a user interface to create and configure forms called
Webforms.

When using forms with private file uploads, Webform wasn't explicitly denying
access to files it managed which could allow access to be granted by other
modules.

The vulnerability is mitigated by the fact that another module has to
explicitly grant access to those files.


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

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

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

  * Webform 7.x-3.x versions prior to 7.x-3.25.
  * Webform 7.x-4.x is unaffected.

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

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

If you use webform-7.x-3.x you may …

  * upgrade to webform 7.x-3.25 [5]
  * upgrade to webform-7.x-4.x but be aware of the backwards incompatible
    changes [6].

Also see the Webform [7] project page.
