6 February 2020
AusCERT Security Bulletin Summary
Product: Drupal Views Bulk Operations plugin
Operating System: Windows
UNIX variants (UNIX, Linux, OSX)
Impact/Access: Unauthorised Access -- Existing Account
- --------------------------BEGIN INCLUDED TEXT--------------------
Views Bulk Operations (VBO) - Moderately critical - Access bypass -
Project: Views Bulk Operations (VBO)
Security risk: Moderately critical 12/25
Vulnerability: Access bypass
Views Bulk Operations provides enhancements to running bulk actions on views.
The module contains an access bypass vulnerability that might allow users to
execute views actions that they should not have access to.
This vulnerability is mitigated by the fact that it only occurs in the case of
customised action access (by means of hook_action_info_alter).
Install the latest version:
* If you use Views Bulk Operations version 3.x for Drupal 8.x, upgrade to
Views Bulk Operations 8.x-3.4
* If you use Views Bulk Operations version 2.x for Drupal 8.x, upgrade to
Views Bulk Operations 8.x-2.6
Also see the Views Bulk Operations (VBO) project page.
