   * Advisory ID: DRUPAL-SA-CONTRIB-2014-078
   * Project: Notify [1]     (third-party module)
   * Version: 7.x
   * Date: 2014-August-13
   * Security risk: 10/25 ( Moderately Critical)
     AC:Complex/A:User/CI:Some/II:None/E:Proof/TD:75 [2]
   * Vulnerability: Access bypass

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

The notify module allows users to subscribe to periodic emails which include
all new or revised content and/or comments of specific content types, much
like the daily newsletters sent by some websites.

The Notify module does not sufficiently check whether the user has access to
recently added or updated nodes and all the fields within the node before
including the nodes in notification emails to a given user. This will expose
node titles and potentially node teasers and fields to users who should not
see them.

This vulnerability is mitigated by the fact that a site must use some form of
access control and must be configured to include nodes with protected content
in notifications.


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

   * /A CVE identifier [3] will be requested, and added upon issuance, in
     accordance
