Project: Date Reminder [1] Date: 2018-November-28 Security risk: *Moderately critical* 10∕25 AC:Basic/A:User/CI:Some/II:None/E:Theoretical/TD:Default [2] Vulnerability: Access bypass

Description:  This module allows registered users to request email reminders to be sent at a specified time before an event.

The module doesn't sufficiently check access to nodes, allowing a user to set a reminder on a node that the user shouldn't be able to access.

This can be mitigated with configuring DateReminder with Reminder Display: "Fieldset within a node" disables the potential exploit.

Solution:  Install the latest version:

* If you use the Date Reminder module for Drupal 7.x, upgrade to Date Reminder 7.x-1.15 [3]

Also see the Date Reminder [4] project page.
