Unspecified vulnerability in Views Bulk Operations 5.x-1.x before 5.x-1.4 and 6.x-1.x before 6.x-1.7, a module for Drupal, allows remote attackers to bypass intended access restrictions and modify "nodes or classes of nodes" via unknown vectors, probably related to registered procedures (aka actions).

The Views Bulk Operations (VBO) module 6.x-1.x and 7.x-3.x before 7.x-3.3 for Drupal, when the bulk operation for changing Roles is enabled, allows remote authenticated users to edit user accounts and add arbitrary roles to the accounts by leveraging access to a user account listing view with VBO enabled.

Unspecified vulnerability in the Views Bulk Operations module 6 before 6.x-1.10 for Drupal allows remote authenticated users with user management permissions to bypass intended access restrictions and delete anonymous users (user 0) via unspecified vectors.
