Booking and Availability Management Tools for Drupal - Moderately critical -
Access Bypass - SA-CONTRIB-2019-074

Project: Booking and Availability Management Tools for Drupal

Date: 2019-October-16

Security risk: Moderately critical 11/25 AC:Basic/A:User/CI:Some/II:None/E:Theoretical/TD:All

Vulnerability: Access Bypass


The Bat module provides a foundation through which a wide range of availability
management, reservation and booking use cases can be addressed.

The routes used to view events don't sufficiently guard access for
non-privileged users. Specifically, a user with the 'View own' permission for
bat events can view others' events as well.


Install the latest version:

  o If you use the bat module for Drupal 8.x, upgrade to bat 8.x-1.2

Also see the Booking and Availability Management Tools for Drupal project page.
