Description

In Drupal versions 8.4.x versions before 8.4.5 the Settings Tray module has a vulnerability that allows users to update certain data that they do not have the permissions for. If you have implemented a Settings Tray form in contrib or a custom module, the correct access checks should be added. This release fixes the only two implementations in core, but does not harden against other such bypasses. This vulnerability can be mitigated by disabling the Settings Tray module.

Affected products

Drupal: from 8.4.0 before 8.4.5 — fixed in 8.4.5

How to fix

Upgrade to a fixed version: Drupal 8.4.5. Check the vendor advisory for mitigations.
