View online: https://www.drupal.org/sa-contrib-2019-074 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.
