   * Advisory ID: DRUPAL-SA-CONTRIB-2014-049
   * Project: Organic groups [1] (third-party module)
   * Version: 7.x
   * Date: 2014-May-07
   * Security risk: Moderately critical [2]
   * Exploitable from: Remote
   * Vulnerability: Access bypass

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

Organic groups (OG) enables users to create and manage their own 'groups'.
Each group can have subscribers, and maintains a group home page where
subscribers communicate amongst themselves.

OG doesn't sufficiently check the permissions when a group member is pending
or blocked status within the group and tries to access information in a site.

This vulnerability only affects sites using the "Organic groups access
control" sub-module available within the Organic Groups package. It's further
mitigated by the fact that an attacker must be pending or blocked.


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

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

-------- VERSIONS AFFECTED
