Permissions, Privileges, and Access Controls
The commons_discussion_views_default_views function in modules/features/commons_discussion/commons_discussion.views_default.inc in the Drupal Commons module 6.x-2.x before 6.x-2.8 for Drupal does not properly enforce intended node access restrictions, which might allow remote attackers to obtain sensitive information via the recent comments listing.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
