- Advisory ID: DRUPAL-SA-CONTRIB-2013-068
- Project: Entity API (third-party module)
- Version: 7.x
- Date: 2013-August-14
- Security risk: Moderately critical
- Exploitable from: Remote
- Vulnerability: Access bypass
Description
The Entity API module extends the entity API of Drupal core in order to provide a unified way to deal with entities and their properties.
The module doesn't sufficiently enforce node access restrictions when checking for a user's access to view a comment associated with a particular node. The vulnerability is mitigated by the fact that it only applies to a user's access to view a comment in a situation where access should be restricted with entity access.
The Entity API also does not properly restrict access when displaying selected entities using the Views field or area plugins, allowing users to view entities that they do not have access to. The vulnerability is mitigated by the fact that entities are only improperly exposed when a View has been configured to display them in a field, header or footer of a View.
