• Advisory ID: DRUPAL-SA-CONTRIB-2012-148
  • Project: Organic groups (third-party module)
  • Version: 7.x
  • Date: 2012-September-26
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Access bypass

Description

OG (Organic groups) 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. A group membership can be given immediately upon subscribing, or be pending - waiting for a group administrator to approve it.

OG doesn't properly maintain pending memberships if the user is allowed to edit their own account.

In addition, under certain circumstances, a user was able to post to a group which they were not a member of.

There are no additional mitigating factors for these issues.
