- Advisory ID: DRUPAL-SA-CONTRIB-2011-050
- Project: Organic groups (third-party module)
- Version: 7.x
- Date: 2011-October-26
- Security risk: Moderately critical
- 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 has an API function to check access to an entity which is in a group "context". When the entity isn't in a group context, OG takes a permissive approach and allows access to the entity. Implementing modules such as Profile2 that try to check access on a non group/group content might result in access bypass
Versions affected
