Overview
Drupal is an open-source content management system known for its flexibility, robust features, and strong community support. Organizations of all sizes use it to build and manage dynamic websites and web applications. The Views Bulk Operation module, which is a popular contributed module in Drupal 7 ecosystem, allows core Actions to be executed on nodes and other entities.
There is a security flaw (specifically, broken access control), in the Views Bulk Operations (VBO) module described in SA-CORE-2025-002 that affects version 8 of Drupal 8 and later. Although Drupal 7 lacks built-in permissions for Actions, the Drupal 7 version of VBO includes the actions_permissions sub-module that provides similar functionality and thus shares this vulnerability.
In Drupal 7, views requiring the 'administer nodes' permission are secure, as this permission grants access to all Actions without needing further safeguards.
However, views accessible to users without 'administer nodes' that enable bulk actions provide full access to execute available bulk actions exposed by that View.
This vulnerability also impacts modules like Admin Views that depend on VBO for functionality.
This issue affects all versions of Views Bulk Operations in the 7.x branch.

Addressing the Issue
Users of the affected component(s) should address this exploit in one of the following ways:
- Mandate the use of the ‘administer nodes' permission; this may not provide sufficient protection thus the next action is recommended instead.
- Enable the Actions Permissions sub-module and enable specific permissions as needed.
