Project: Booking and Availability Management Tools for Drupal [1]
Date: 2019-October-16
Security risk: *Moderately critical* 11∕25
AC:Basic/A:User/CI:Some/II:None/E:Theoretical/TD:All [2]
Vulnerability: Access Bypass

Description: 
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.

Solution: 
Install the latest version:

   * If you use the bat module for Drupal 8.x, upgrade to bat 8.x-1.2 [3]

Also see the Booking and Availability Management Tools for Drupal [4] project
page.
