Views Bulk Operations (VBO) - Moderately critical - Access bypass -
SA-CONTRIB-2020-003

Project: Views Bulk Operations (VBO)
Date: 2020-February-05
Security risk: Moderately critical 12/25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/
TD:Uncommon
Vulnerability: Access bypass
Description: 

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).

Solution: 

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.
